Enables

This protein enables 8 target(s):

TargetCategoryDefinition
magnesium ion bindingmolecular functionBinding to a magnesium (Mg) ion. [GOC:ai]
protein serine/threonine kinase activitymolecular functionCatalysis of the reactions: ATP + protein serine = ADP + protein serine phosphate, and ATP + protein threonine = ADP + protein threonine phosphate. [GOC:bf, MetaCyc:PROTEIN-KINASE-RXN, PMID:2956925]
AMP-activated protein kinase activitymolecular functionCatalysis of the reaction: ATP + a protein = ADP + a phosphoprotein. This reaction requires the presence of AMP. [GOC:mah]
cAMP-dependent protein kinase activitymolecular functioncAMP-dependent catalysis of the reaction: ATP + a protein = ADP + a phosphoprotein. [EC:2.7.11.11]
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]
ubiquitin protein ligase bindingmolecular functionBinding to a ubiquitin protein ligase enzyme, any of the E3 proteins. [GOC:vp]
protein serine kinase activitymolecular functionCatalysis of the reactions: ATP + protein serine = ADP + protein serine phosphate. [RHEA:17989]

Located In

This protein is located in 6 target(s):

TargetCategoryDefinition
nucleoplasmcellular componentThat part of the nuclear content other than the chromosomes or the nucleolus. [GOC:ma, ISBN:0124325653]
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]
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]
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]
ciliary basecellular componentArea of the cilium (also called flagellum) where the basal body and the axoneme are anchored to the plasma membrane. The ciliary base encompasses the distal part of the basal body, transition fibers and transition zone and is structurally and functionally very distinct from the rest of the cilium. In this area proteins are sorted and filtered before entering the cilium, and many ciliary proteins localize specifically to this area. [GOC:cilia, GOC:krc, PMID:22653444]

Active In

This protein is active in 2 target(s):

TargetCategoryDefinition
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]
nucleuscellular componentA membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent. [GOC:go_curators]

This protein is part of 1 target(s):

TargetCategoryDefinition
cAMP-dependent protein kinase complexcellular componentAn enzyme complex, composed of regulatory and catalytic subunits, that catalyzes protein phosphorylation. Inactive forms of the enzyme have two regulatory chains and two catalytic chains; activation by cAMP produces two active catalytic monomers and a regulatory dimer. [PMID:18178622]

Involved In

This protein is involved in 10 target(s):

TargetCategoryDefinition
neural tube closurebiological processThe last step in the formation of the neural tube, where the paired neural folds are brought together and fuse at the dorsal midline. [GOC:dph, ISBN:0878932437]
renal water homeostasisbiological processRenal process involved in the maintenance of an internal steady state of water in the body. [GOC:mtg_cardio]
protein phosphorylationbiological processThe process of introducing a phosphate group on to a protein. [GOC:hb]
signal transductionbiological processThe cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell. Signal transduction begins with reception of a signal (e.g. a ligand binding to a receptor or receptor activation by a stimulus such as light), or for signal transduction in the absence of ligand, signal-withdrawal or the activity of a constitutively active receptor. Signal transduction ends with regulation of a downstream cellular process, e.g. regulation of transcription or regulation of a metabolic process. Signal transduction covers signaling from receptors located on the surface of the cell and signaling via molecules located within the cell. For signaling between cells, signal transduction is restricted to events at and within the receiving cell. [GOC:go_curators, GOC:mtg_signaling_feb11]
adenylate cyclase-modulating G protein-coupled receptor signaling pathwaybiological processA G protein-coupled receptor signaling pathway in which the signal is transmitted via the activation or inhibition of adenylyl cyclase activity and a subsequent change in the intracellular concentration of cyclic AMP (cAMP). [GOC:mah, GOC:signaling, ISBN:0815316194]
high-density lipoprotein particle assemblybiological processThe non-covalent aggregation and arrangement of proteins and lipids to form a high-density lipoprotein particle. [GOC:BHF, GOC:mah]
negative regulation of smoothened signaling pathwaybiological processAny process that stops, prevents, or reduces the frequency, rate or extent of smoothened signaling. [GOC:go_curators]
regulation of protein processingbiological processAny process that modulates the frequency, rate or extent of protein processing, a protein maturation process achieved by the cleavage of a peptide bond or bonds within a protein. [GOC:mah]
negative regulation of TORC1 signalingbiological processAny process that stops, prevents or reduces the frequency, rate or extent of TORC1 signaling. [GO_REF:0000058, GOC:TermGenie, PMID:25366275]
protein kinase A signalingbiological processAn intracellular signaling cassette that starts with the activation of protein kinase A (PKA), and ends with the regulation of a downstream cellular process, e.g. transcription. The PKA catalytic subunit (PKA-C) is normally present in a complex with its regulatory subunit, PKA-R. The inhibitory action of PKA-R is released upon cAMP binding, which results in the activation of PKA-C. [PMID:35252178, PMID:36431013]
