Disease

CISD2_HUMAN Defects in CISD2 are the cause of Wolfram syndrome type 2 (WFS2) [MIM:604928. A rare disorder characterized by juvenile-onset insulin-dependent diabetes mellitus with optic atrophy. Other manifestations include diabetes insipidus, sensorineural deafness, dementia, psychiatric illnesses. WFS2 patients additionally show a strong bleeding tendency and gastrointestinal ulceration. Diabetes insipidus may be absent.^[1]

Function

CISD2_HUMAN Regulator of autophagy that contributes to antagonize BECN1-mediated cellular autophagy at the endoplasmic reticulum. Participates in the interaction of BCL2 with BECN1 and is required for BCL2-mediated depression of endoplasmic reticulum Ca(2+) stores during autophagy. Contributes to BIK-initiated autophagy, while it is not involved in BIK-dependent activation of caspases. Involved in life span control, probably via its function as regulator of autophagy.^[2] ^[3]
