Predicted to enable transmembrane transporter binding activity. Predicted to be involved in positive regulation of calcineurin-NFAT signaling cascade and release of sequestered calcium ion into cytosol. Predicted to act upstream of or within negative regulation of cell population proliferation. Predicted to be located in sarcoplasmic reticulum membrane. Predicted to be active in perinuclear region of cytoplasm. Is expressed in embryo and extraembryonic component. Orthologous to human CHERP (calcium homeostasis endoplasmic reticulum protein).
