Description

Description générale

STIM1 (stromal interaction molecule 1) is a transmembrane protein, which spans the membrane once. It predominantly resides in endoplasmic reticulum (ER), though some of it is found in the plasma membrane. It has a canonical EF-hand (cEF) domain, two EF-hand domains, a hidden non Ca²⁺ binding EF-hand domain (hEF), and a sterile α motif (SAM). This is present in the N-terminal of the protein, which is located towards the lumen of ER. This gene is localized to human chromosome 11p15.5, and encodes a protein of 90kDa molecular weight, which is ubiquitously expressed.

Immunogène

Stromal interaction molecule 1 precursor recombinant protein epitope signature tag (PrEST)

Application

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project and as a result, are supported by the most extensive characterization in the industry.

The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. We also provide Prestige Antibodies^® protocols and other useful information.

Actions biochimiques/physiologiques

STIM1 (stromal interaction molecule 1) is an integral part of SOCE (Store-operated Ca²⁺ entry), which is a Ca²⁺ entry gateway in non-excitable cells. Orai1, which is a Ca²⁺ channel present on plasma membrane, interacts with STIM1 present on ER, through SOAR/CAD domain present in the C-terminal of STIM1. Whenever Ca²⁺ levels fall low in ER, STIM1 changes to an extended conformation of C-terminal to expose SOAR/CAD domain. Also Ca²⁺ depletion leads to oligomerization of STIM1, through unfolding of the EF-SAM domain. STIM1 present on plasma membrane also regulates Ca²⁺ entry through opening of arachidonic acid calcium (ARC) channels. It acts as a tumor suppressor gene, and its expression is related to various malignancies. Studies show that up-regulation of this gene leads to tumor arrest in G401 rhabdoid tumor, rhabdomyosarcoma and rodent myoblast cell lines.

Caractéristiques et avantages

Prestige Antibodies^® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies^® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:

• IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
• Protein array of 364 human recombinant protein fragments.
