Background Information
Store-operated calcium channels (SOCs) play essential functions in various physiological processes. Orai1 (also named CRACM1) is a critical molecular component of SOCs. Orai1 protein is a 35-45 kDa plasma membrane protein with 4 transmembrane domains. Human patients with a severe combinaed immunodeficiency (SCID) syndrome possess point mutations in Orai1 gene. This antibody may be used to block the ion currents mediated by Orai1. ORAI1 contains 2 isoforms produced by alternative initiation(uniprot: Q96D31). Catalog#14443-1-AP only recognises alpha isoform.
