Genes affected

CHERP (HGNC:16930): (calcium homeostasis endoplasmic reticulum protein) Enables transmembrane transporter binding activity. Involved in positive regulation of calcineurin-NFAT signaling cascade and release of sequestered calcium ion into cytosol. Acts upstream of or within cellular calcium ion homeostasis and negative regulation of cell population proliferation. Located in perinuclear region of cytoplasm.
