Beschreibung

General description

Stromal interaction molecule 1 (STIM1) is a conserved single-pass transmembrane protein. STIM1 is expressed ubiquitously in a wide variety of human primary and transformed cell types. STIM1 localizes 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 657-683 of human STIM1, conjugated to KLH via an N-terminal residue. The corresponding sequence is identical in rat, mouse, bovine, monkey, and dog.

Application

Anti-STIM1 (C-terminal) antibody produced in rabbit has been used in:

• western blot
• immunoprecipitation
• immunofluorescence
• immunohistochemistry

Biochem/physiol Actions

Stromal interaction molecule 1 (STIM1) is required for the activation of store-operated Ca²⁺ influx. STIM1 undergoes rapid oligomerization and redistributes into discrete spots (punctae) that move towards and accumulate in the cell periphery, possibly to activate Orai1 that is located in the plasma membrane. Overexpression of STIM1 and Orai1 together markedly increases the calcium release-activated channels (CRAC) current (I-CRAC). Dynamic assembly of TRPC1-STIM1-Orai1 ternary complex plays a major role in the activation of store-operated calcium (SOC) channel in response to internal Ca²⁺ store depletion.

Physical form

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