Enables

This protein enables 3 target(s):

TargetCategoryDefinition
protein bindingmolecular functionBinding to a protein. [GOC:go_curators]
protein heterodimerization activitymolecular functionBinding to a nonidentical protein to form a heterodimer. [GOC:ai]
alpha1-adrenergic receptor activitymolecular functionCombining with epinephrine or norepinephrine to initiate a change in cell activity via activation of a G protein, with pharmacological characteristics of alpha1-adrenergic receptors; the activity involves transmitting the signal to the Gq alpha subunit of a heterotrimeric G protein. [GOC:cb, GOC:mah, IUPHAR_GPCR:1274]

Located In

This protein is located in 5 target(s):

TargetCategoryDefinition
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]
cytoplasmcellular componentThe contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. [ISBN:0198547684]
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]
caveolacellular componentA membrane raft that forms small pit, depression, or invagination that communicates with the outside of a cell and extends inward, indenting the cytoplasm and the cell membrane. Examples include flask-shaped invaginations of the plasma membrane in adipocytes associated with caveolin proteins, and minute pits or incuppings of the cell membrane formed during pinocytosis. Caveolae may be pinched off to form free vesicles within the cytoplasm. [GOC:mah, ISBN:0721662544, PMID:16645198]
nuclear membranecellular componentEither of the lipid bilayers that surround the nucleus and form the nuclear envelope; excludes the intermembrane space. [GOC:mah, GOC:pz]

Involved In

This protein is involved in 11 target(s):

TargetCategoryDefinition
G protein-coupled receptor signaling pathwaybiological processThe series of molecular signals initiated by a ligand binding to its receptor, in which the activated receptor promotes the exchange of GDP for GTP on the alpha-subunit of an associated heterotrimeric G-protein complex. The GTP-bound activated alpha-G-protein then dissociates from the beta- and gamma-subunits to further transmit the signal within the cell. The pathway begins with receptor-ligand interaction, and ends with regulation of a downstream cellular process. The pathway can start from the plasma membrane, Golgi or nuclear membrane. [GOC:bf, GOC:mah, PMID:16902576, PMID:24568158, Wikipedia:G_protein-coupled_receptor]
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]
regulation of vasoconstrictionbiological processAny process that modulates the frequency, rate or extent of reductions in the diameter of blood vessels. [GOC:jl]
intracellular signal transductionbiological processThe process in which a signal is passed on to downstream components within the cell, which become activated themselves to further propagate the signal and finally trigger a change in the function or state of the cell. [GOC:bf, GOC:jl, GOC:signaling, ISBN:3527303782]
positive regulation of MAPK cascadebiological processAny process that activates or increases the frequency, rate or extent of signal transduction mediated by the MAPK cascade. [GOC:go_curators]
regulation of cardiac muscle contractionbiological processAny process that modulates the frequency, rate or extent of cardiac muscle contraction. [GOC:ecd]
neuron-glial cell signalingbiological processCell-cell signaling that mediates the transfer of information from a neuron to a glial cell. This signaling has been shown to be mediated by various molecules released by different types of neurons, e.g. glutamate, gamma-amino butyric acid (GABA), noradrenaline, acetylcholine, dopamine and adenosine. [GOC:aruk, GOC:bc, PMID:10195197, PMID:10196584, PMID:10377338, PMID:10493741, PMID:11356870, PMID:11399439, PMID:15252819, PMID:27788368]
adenylate cyclase-activating adrenergic receptor signaling pathwaybiological processAn adenylate cyclase-activating G protein-coupled receptor signaling pathway initiated by a ligand binding to an adrenergic receptor on the surface of the target cell, and ending with the regulation of a downstream cellular process. [GOC:BHF, GOC:mah, GOC:signaling]
cell-cell signalingbiological processAny process that mediates the transfer of information from one cell to another. This process includes signal transduction in the receiving cell and, where applicable, release of a ligand and any processes that actively facilitate its transport and presentation to the receiving cell. Examples include signaling via soluble ligands, via cell adhesion molecules and via gap junctions. [GOC:dos, GOC:mah]
phospholipase C-activating G protein-coupled receptor signaling pathwaybiological processA G protein-coupled receptor signaling pathway in which the signal is transmitted via the activation of phospholipase C (PLC) and a subsequent increase in the intracellular concentration of inositol trisphosphate (IP3) and diacylglycerol (DAG). [GOC:dph, GOC:mah, GOC:signaling, GOC:tb, ISBN:0815316194]
positive regulation of cytosolic calcium ion concentrationbiological processAny process that increases the concentration of calcium ions in the cytosol. [GOC:ai]
