Crystal Structure of Miner1: The Redox-active 2Fe-2S Protein Causative in Wolfram Syndrome 2
Template:ABSTRACT PUBMED 19580816
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]
About this Structure
3fnv is a 2 chain structure with sequence from Homo sapiens. Full crystallographic information is available from OCA.
