SOAR
PFAM accession number:PF16533
Interpro abstract (IPR032393):

This domain, also known as SOAR, is the Orai1-activating region of STIM1 (stromal interaction molecule 1). STIM1 is a Ca2+ sensor in the endoplasmic reticulum. As the store of calcium is depleted the calcium sensor in the ER activates Orai1, a Ca2+-release-activated Ca2+ (CRAC) channel, in the plasma membrane. The SOAR region forms a dimer, and is essential for oligomerisation of the whole of STIM1 [(PUBMED:22451904)].

This is a PFAM domain. For full annotation and more information, please see the PFAM entry SOAR
