| inositol 1,4,5-trisphosphate-gated calcium channel activity | molecular function | Enables the transmembrane transfer of a calcium ion by a channel that opens when inositol 1,4,5-trisphosphate (IP3) has been bound by the channel complex or one of its constituent parts. [GOC:mah, GOC:signaling, PMID:28416699, PMID:8660280, Wikipedia:Inositol_trisphosphate_receptor] |
| calcium ion transmembrane transporter activity | molecular function | Enables the transfer of calcium (Ca) ions from one side of a membrane to the other. [GOC:dgf, RHEA:29671] |
| transmembrane transporter binding | molecular function | Binding 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] |
| scaffold protein binding | molecular function | Binding to a scaffold protein. Scaffold proteins are crucial regulators of many key signaling pathways. Although not strictly defined in function, they are known to interact and/or bind with multiple members of a signaling pathway, tethering them into complexes. [GOC:BHF, GOC:sjp, PMID:10433269, Wikipedia:Scaffold_protein] |

This protein is located in 8 target(s):
| Target | Category | Definition |
|---|---|---|
| nucleoplasm | cellular component | That part of the nuclear content other than the chromosomes or the nucleolus. [GOC:ma, ISBN:0124325653] |
| endoplasmic reticulum | cellular component | The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached). [ISBN:0198506732] |
| endoplasmic reticulum membrane | cellular component | The lipid bilayer surrounding the endoplasmic reticulum. [GOC:mah] |
| plasma membrane | cellular component | The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. [ISBN:0716731363] |
| cell cortex | cellular component | The region of a cell that lies just beneath the plasma membrane and often, but not always, contains a network of actin filaments and associated proteins. [GOC:mah, ISBN:0815316194] |
| membrane | cellular component | A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it. [GOC:dos, GOC:mah, ISBN:0815316194] |

This protein is involved in 6 target(s):
| Target | Category | Definition |
|---|---|---|
| response to hypoxia | biological process | Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus indicating lowered oxygen tension. Hypoxia, defined as a decline in O2 levels below normoxic levels of 20.8 - 20.95%, results in metabolic adaptation at both the cellular and organismal level. [GOC:hjd] |
| signal transduction | biological process | The 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] |
| calcium-mediated signaling | biological process | Any intracellular signal transduction in which the signal is passed on within the cell via calcium ions. [GOC:signaling] |
| release of sequestered calcium ion into cytosol | biological process | The process in which calcium ions sequestered in the endoplasmic reticulum, Golgi apparatus or mitochondria are released into the cytosolic compartment. [GOC:dph, GOC:hjd, GOC:mtg_lung, PMID:1814929] |
| cellular response to cAMP | biological process | Any 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 cAMP (cyclic AMP, adenosine 3',5'-cyclophosphate) stimulus. [GOC:mah] |
| cellular response to ethanol | biological process | Any 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 an ethanol stimulus. [GOC:mah] |
