Summaries for ISCA1 Gene

Entrez Gene Summary for ISCA1 Gene

  • ISCA1 is a mitochondrial protein involved in the biogenesis and assembly of iron-sulfur clusters, which play a role in electron-transfer reactions (Cozar-Castellano et al., 2004 [PubMed 15262227]).[supplied by OMIM, Mar 2008]

GeneCards Summary for ISCA1 Gene

ISCA1 (Iron-Sulfur Cluster Assembly 1) is a Protein Coding gene. GO annotations related to this gene include structural molecule activity and iron-sulfur cluster binding.

UniProtKB/Swiss-Prot for ISCA1 Gene

  • Involved in the maturation of mitochondrial 4Fe-4S proteins functioning late in the iron-sulfur cluster assembly pathway. Probably involved in the binding of an intermediate of Fe/S cluster assembly.
