General description

STIM1 (stromal interaction molecule 1) is a conserved single-pass transmembrane protein, which is expressed ubiquitously in a wide variety of human primary and transformed cell types. STIM1 is modified by phosphorylation and N-linked glycosylation. STIM1 localized predominantly in the membrane of the endoplasmic reticulum (ER). It contains an N-terminal EF hand motif located in the ER lumen and appears to function as a sensor of ER Ca2+ levels.

Immunogen

synthetic peptide corresponding to amino acids 61-74 of human STIM1, conjugated to KLH via a C-terminal cysteine residue. The corresponding sequence is identical in rat and mouse.

Application

Anti-STIM1 (N-terminal) antibody produced in rabbit has been used in:
  • western blotting
  • immunoprecipitation
  • immunofluorescence

Biochem/physiol Actions

STIM1 (stromal interaction molecule 1) is required for the activation of store-operated Ca2+ influx. Overexpression of STIM1 and Orai1 markedly increases the calcium release-activated calcium (CRAC) current (I-CRAC).

Physical form

Solution in 0.01 M phosphate buffered saline, 7.4 pH, containing 15 mM sodium azide.
