Summary: Enables iron ion binding activity. Involved in biotin biosynthetic process; iron-sulfur cluster assembly; and protein maturation by [4Fe-4S] cluster transfer. Located in mitochondrial intermembrane space and mitochondrial matrix. Human ortholog(s) of this gene implicated in multiple mitochondrial dysfunctions syndrome 4. Orthologous to human ISCA2 (iron-sulfur cluster assembly 2). [provided by Alliance of Genome Resources, Apr 2022]

What's a GeneRIF?

A novel substrate, Isa2, is likely processed by Icp55 in two consecutive steps and thus might represent the first example of a triple processing event in a mitochondrial precursor protein.
Title: Novel highly sensitive, specific, and straightforward strategy for comprehensive N-terminal proteomics reveals unknown substrates of the mitochondrial peptidase Icp55.
define Isa1, Isa2, and Iba57 as a specialized, late-acting ISC assembly subsystem that is specifically dedicated to the maturation of mitochondrial [4Fe-4S] proteins.
