KRAP_IP3R_bindKi-ras-induced actin-interacting protein-IP3R-interacting domain
|SMART accession number:||SM01257
||This family includes the N-terminus of the actin-interacting protein sperm-specific antigen 2, or KRAP (Ki-ras-induced actin-interacting protein) (PUBMED:14673706). This region is found to be the residues that interact with inositol 1,4,5-trisphosphate receptor (IP3R). KRAP was first localized as a membrane-bound form with extracellular regions suggesting it might be involved in the regulation of filamentous actin and signals from the outside of the cells (PUBMED:14673706). It has now been shown to be critical for the proper subcellular localization and function of IP3R. Inositol 1,4,5-trisphosphate receptor functions as the Ca2+ release channel on specialized endoplasmic reticulum membranes, so the subcellular localisation of IP3R is crucial for its proper function (PUBMED:21501587).|
