The sca-1 gene encodes a sarco-endoplasmic reticulum Ca[2+] ATPase homolog that is required for development and muscle function; sca-1 is also a ortholog of human ATP2A1 (OMIM:108730), which when mutated leads to Darier-White disease (OMIM:124200).
Enables P-type calcium transporter activity and chromatin DNA binding activity. Involved in several processes, including IRE1-mediated unfolded protein response; calcium ion import; and chemical homeostasis. Located in cytoplasmic vesicle and endomembrane system. Expressed in several structures, including egg-laying apparatus; excretory system; intestine; non-striated muscle; and spermatheca. Human ortholog(s) of this gene implicated in Brody myopathy; hypertension (multiple); and keratosis (multiple). Is an ortholog of human ATP2A3 (ATPase sarcoplasmic/endoplasmic reticulum Ca2+ transporting 3).
