<i>STIM1</i> Mutation Associated with a Syndrome of Immunodeficiency and Autoimmunity
6 May 2009
Abstract excerpt
A mutation in ORAI1, the gene encoding the pore-forming subunit of the Ca(2+)-release-activated Ca(2+) (CRAC) channel, abrogates the store-operated entry of Ca(2+) into cells and impairs lymphocyte activation. Stromal interaction molecule 1 (STIM1) in the endoplasmic reticulum activates ORAI1-CRAC channels. We report on three siblings from one kindred with a clinical syndrome of immunodeficiency,...
