caution:Although initially though (PubMed:17846994) to be a zinc-finger protein, it was later shown (PubMed:17376863) that it binds 1 2Fe-2S cluster instead.,cofactor:Binds 1 2Fe-2S cluster.,disease:Defects in CISD2 are the cause of Wolfram syndrome 2 (WFS2) [MIM:604928]. WFS2 is a rare autosomal recessive disorder characterized by characterized by optic atrophy and diabetes mellitus. Other symptoms include the presence of profound upper gastrointestinal ulceration, significant bleeding tendency, defective platelet aggregation with collagen and various neurological symptoms.,function:May play a role in calcium homeostasis.,similarity:Belongs to the CISD protein family.,tissue specificity:Testis, small intestine, kidney, lung, brain, heart, pancreas and platelets.,
Endoplasmic reticulum membrane; Single-pass membrane protein. Mitochondrion outer membrane; Single-pass membrane protein. According to PubMed:20010695, it mainly localizes to the endoplasmic reticulum. However, experiments in mouse showed that it mainly localizes to the mitochondrion outer membrane.
Testis, small intestine, kidney, lung, brain, heart, pancreas and platelets.
