半岛bd体育手机客户端 说明

一般描述

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 andN-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.

免疫原

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.

应用

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

• western blotting
• immunoprecipitation
• immunofluorescence

生化/生理作用

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).

外形

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