Entrez ID 150274
Gene name HscB mitochondrial iron-sulfur cluster cochaperone
Gene symbol HSCB
Synonyms (NCBI Gene)
DNAJC20HSC20JAC1SIDBA5
Chromosome 22
Chromosome location 22q12.1
Summary This gene encodes a DnaJ-type co-chaperone and member of the heat shock cognate B (HscB) family of proteins. The encoded protein plays a role in the synthesis of iron-sulfur clusters, protein cofactors that are involved in the redox reactions of mitochond
