protein tyrosine kinase activitymolecular functionCatalysis of the reaction: ATP + a protein tyrosine = ADP + protein tyrosine phosphate. [RHEA:10596]
non-membrane spanning protein tyrosine kinase activitymolecular functionCatalysis of the reaction: ATP + protein L-tyrosine = ADP + protein L-tyrosine phosphate by a non-membrane spanning protein. [EC:2.7.10.2]
protein bindingmolecular functionBinding to a protein. [GOC:go_curators]
ATP bindingmolecular functionBinding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator. [ISBN:0198506732]
enzyme bindingmolecular functionBinding to an enzyme, a protein with catalytic activity. [GOC:jl]
transmembrane transporter bindingmolecular functionBinding to a transmembrane transporter, a protein or protein complex that enables the transfer of a substance, usually a specific substance or a group of related substances, from one side of a membrane to the other. [GOC:BHF, GOC:jl, PMID:33199372]
signaling receptor bindingmolecular functionBinding to one or more specific sites on a receptor molecule, a macromolecule that undergoes combination with a hormone, neurotransmitter, drug or intracellular messenger to initiate a change in cell function. [GOC:bf, GOC:ceb, ISBN:0198506732]

Located In

This protein is located in 7 target(s):

TargetCategoryDefinition
Golgi apparatuscellular componentA membrane-bound cytoplasmic organelle of the endomembrane system that further processes the core oligosaccharides (e.g. N-glycans) added to proteins in the endoplasmic reticulum and packages them into membrane-bound vesicles. The Golgi apparatus operates at the intersection of the secretory, lysosomal, and endocytic pathways. [ISBN:0198506732]
centrosomecellular componentA structure comprised of a core structure (in most organisms, a pair of centrioles) and peripheral material from which a microtubule-based structure, such as a spindle apparatus, is organized. Centrosomes occur close to the nucleus during interphase in many eukaryotic cells, though in animal cells it changes continually during the cell-division cycle. [GOC:mah, ISBN:0198547684]
cytosolcellular componentThe part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. [GOC:hjd, GOC:jl]
actin filamentcellular componentA filamentous structure formed of a two-stranded helical polymer of the protein actin and associated proteins. Actin filaments are a major component of the contractile apparatus of skeletal muscle and the microfilaments of the cytoskeleton of eukaryotic cells. The filaments, comprising polymerized globular actin molecules, appear as flexible structures with a diameter of 5-9 nm. They are organized into a variety of linear bundles, two-dimensional networks, and three dimensional gels. In the cytoskeleton they are most highly concentrated in the cortex of the cell just beneath the plasma membrane. [GOC:mah, ISBN:0198506732, PMID:10666339]
plasma membranecellular componentThe membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. [ISBN:0716731363]
focal adhesioncellular componentA cell-substrate junction that anchors the cell to the extracellular matrix and that forms a point of termination of actin filaments. In insects focal adhesion has also been referred to as hemi-adherens junction (HAJ). [GOC:aruk, GOC:bc, ISBN:0124325653, ISBN:0815316208, PMID:10419689, PMID:12191915, PMID:15246682, PMID:1643657, PMID:16805308, PMID:19197329, PMID:23033047, PMID:26923917, PMID:28796323, PMID:8314002]
extracellular exosomecellular componentA vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm. [GOC:BHF, GOC:mah, GOC:vesicles, PMID:15908444, PMID:17641064, PMID:19442504, PMID:19498381, PMID:22418571, PMID:24009894]

plasma membranecellular componentThe membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. [ISBN:0716731363]

Involved In

This protein is involved in 17 target(s):

TargetCategoryDefinition
negative regulation of inflammatory response to antigenic stimulusbiological processAny process that stops, prevents, or reduces the frequency, rate, or extent of an inflammatory response to an antigenic stimulus. [GOC:add]
regulation of glucose transmembrane transportbiological processAny process that modulates the frequency, rate or extent of glucose transport across a membrane. Glucose transport is the directed movement of the hexose monosaccharide glucose into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. [GOC:dph, GOC:tb]
T cell costimulationbiological processThe process of providing, via surface-bound receptor-ligand pairs, a second, antigen-independent, signal in addition to that provided by the T cell receptor to augment T cell activation. [ISBN:0781735149]
cellular response to platelet-derived growth factor stimulusbiological processAny process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a platelet-derived growth factor stimulus. [GOC:yaf]
protein modification processbiological processThe covalent alteration of one or more amino acids occurring in proteins, peptides and nascent polypeptides (co-translational, post-translational modifications). Includes the modification of charged tRNAs that are destined to occur in a protein (pre-translation modification). [GOC:bf, GOC:jl]
Fc-gamma receptor signaling pathway involved in phagocytosisbiological processAn Fc-gamma receptor signaling pathway that contributes to the endocytic engulfment of external particulate material by phagocytes. [GOC:phg, PMID:12488490, PMID:15466916]
regulation of vascular permeabilitybiological processAny process that modulates the extent to which blood vessels can be pervaded by fluid. [GOC:jl]
positive regulation of transcription by RNA polymerase IIbiological processAny process that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter. [GOC:go_curators, GOC:txnOH]
ephrin receptor signaling pathwaybiological processThe series of molecular signals initiated by ephrin binding to its receptor, and ending with the regulation of a downstream cellular process, e.g. transcription. [GOC:ceb]
positive regulation of peptidyl-tyrosine phosphorylationbiological processAny process that activates or increases the frequency, rate or extent of the phosphorylation of peptidyl-tyrosine. [GOC:ai]
leukocyte migrationbiological processThe movement of a leukocyte within or between different tissues and organs of the body. [GOC:add, ISBN:0781735149, PMID:14680625, PMID:14708592, PMID:7507411, PMID:8600538]
cellular response to retinoic acidbiological processAny process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a retinoic acid stimulus. [GOC:mah]
cellular response to transforming growth factor beta stimulusbiological processAny process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a transforming growth factor beta stimulus. [GOC:ecd, PMID:15451575]
innate immune responsebiological processInnate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens. [GO_REF:0000022, GOC:add, GOC:ebc, GOC:mtg_sensu]
cell differentiationbiological processThe cellular developmental process in which a relatively unspecialized cell, e.g. embryonic or regenerative cell, acquires specialized structural and/or functional features that characterize a specific cell. Differentiation includes the processes involved in commitment of a cell to a specific fate and its subsequent development to the mature state. [ISBN:0198506732]
cell surface receptor protein tyrosine kinase signaling pathwaybiological processThe series of molecular signals initiated by an extracellular ligand binding to a receptor on the surface of the target cell where the receptor possesses tyrosine kinase activity, and ending with the regulation of a downstream cellular process, e.g. transcription. [GOC:ceb, GOC:signaling]
protein phosphorylationbiological processThe process of introducing a phosphate group on to a protein. [GOC:hb]
