Ca signals control many cellular functions ranging from short-term responses such as contraction and secretion to longer-term regulation of cell growth and proliferation (1,2). Stromal interaction molecules (STIMs) function as Ca sensors that detect changes in Ca content in intracellular Ca stores (3). STIM1 is conserved, ubiquitously expressed, and functions as an endoplasmic reticulum (ER) Ca sensor that migrates from the ER Ca store to the plasma membrane where it activates calcium-release-activated calcium (CRAC) channels when the ER Ca store is low (4). STIM1 is a potential tumor suppressor; defects in STIM1 may cause rhabdomyosarcoma and rhabdoid tumors (5). STIM1 can either homodimerize or form heterodimers with STIM2. STIM2 possesses a high sequence identity to STIM1 and can function as an inhibitor of STIM1-mediated plasma membrane store-operated Ca entry (6). However, further investigation is required to elucidate the true physiological function of STIM2.\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nFLJ39527; KIAA1482; STIM2; Stromal interaction molecule 2\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R Mk\nSENSITIVITY: Endogenous\nMW (kDa): 100\nSOURCE: Rabbit","brand":"CST","offers":[{"title":"Default Title","offer_id":46799680733353,"sku":"4917S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-4917s","provider":"Iright","version":"1.0","type":"link"}
