FATE1

Function

Involved in the regulation of endoplasmic reticulum (ER)-mitochondria coupling. Negatively regulates the ER-mitochondria distance and Ca(2+) transfer from ER to mitochondria possibly implicating it in the regulation of apoptosis (PubMed:27402544). May collaborate with RNF183 to restrain BIK protein levels thus regulating apoptotic signaling (PubMed:26567849).

Tissue specificity

Testis-specific in fetus (aged from 6 to 11 weeks). In adult, expressed predominantly in testis, with some expression in lung, heart, kidney, adrenal gland and whole brain (PubMed:11694338). Highly expressed in certain types of cancer tissues such as hepatocellular carcinoma, colon and gastric cancer. Weakly expressed in normal pancreas (PubMed:12865919).

Cellular localization

• Mitochondrion
• Mitochondrion outer membrane
• Endoplasmic reticulum membrane
• Single-pass membrane protein
• Cytoplasmic side
• Localized to specific membrane structures termed mitochondria-associated membranes (MAMs) which connect the endoplasmic reticulum (ER) and the mitochondria. Also associated with the outer surface of mitochondria at sites that are not in close contact with the ER.

Alternative names

• Fetal and adult testis-expressed transcript protein
• Cancer/testis antigen 43
• Tumor antigen BJ-HCC-2
• CT43
• FATE
• FATE1
