Background
| Function | FUNCTION: Acts as a co-chaperone in iron-sulfur cluster assembly in both mitochondria and the cytoplasm (PubMed:20668094, PubMed:29309586). Required for incorporation of iron-sulfur clusters into SDHB, the iron-sulfur protein subunit of succinate dehydrogenase that is involved in complex II of the mitochondrial electron transport chain (PubMed:26749241). Recruited to SDHB by interaction with SDHAF1 which first binds SDHB and then recruits the iron-sulfur transfer complex formed by HSC20, HSPA9 and ISCU through direct binding to HSC20 (PubMed:26749241). Also mediates complex formation between components of the cytosolic iron-sulfur biogenesis pathway and the CIA targeting complex composed of CIAO1, DIPK1B/FAM69B and MMS19 by binding directly to the scaffold protein ISCU and to CIAO1 (PubMed:29309586). This facilitates iron-sulfur cluster insertion into a number of cytoplasmic and nuclear proteins including POLD1, ELP3, DPYD and PPAT (PubMed:29309586). {ECO:0000269|PubMed:20668094, ECO:0000269|PubMed:26749241, ECO:0000269|PubMed:29309586}. |
| Pathway | Cofactor biosynthesis; iron-sulfur cluster biosynthesis. |
| Protein Families | HscB family |
| Tissue Specificity | Expressed in lung, brain, stomach, spleen, ovary, testis, liver, muscle and heart. {ECO:0000269|PubMed:12938016, ECO:0000269|PubMed:20668094}. |
