CC -!- FUNCTION: Component of the cytosolic iron-sulfur (Fe-S) protein
CC assembly (CIA) machinery required for the maturation of
CC extramitochondrial Fe-S proteins. Part of an electron transfer chain
CC functioning in an early step of cytosolic Fe-S biogenesis, facilitating
CC the de novo assembly of a [4Fe-4S] cluster on the scaffold complex
CC NUBP1-NUBP2. Electrons are transferred to CIAPIN1 from NADPH via the
CC FAD- and FMN-containing protein NDOR1. NDOR1-CIAPIN1 are also required
CC for the assembly of the diferric tyrosyl radical cofactor of
CC ribonucleotide reductase (RNR), probably by providing electrons for
CC reduction during radical cofactor maturation in the catalytic small
CC subunit. Has anti-apoptotic effects in the cell. Involved in negative
CC control of cell death upon cytokine withdrawal. Promotes development of
CC hematopoietic cells. {ECO:0000255|HAMAP-Rule:MF_03115}.

CC Name=[2Fe-2S] cluster; Xref=ChEBI:CHEBI:190135;

CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_03115};
CC -!- SUBUNIT: Monomer. Interacts with ndor1. Interacts with chchd4.
CC {ECO:0000255|HAMAP-Rule:MF_03115}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_03115}.
CC Nucleus {ECO:0000255|HAMAP-Rule:MF_03115}. Mitochondrion intermembrane
CC space {ECO:0000255|HAMAP-Rule:MF_03115}.
CC -!- DOMAIN: The twin Cx2C motifs are involved in the recognition by the
CC mitochondrial CHCHD4/MIA40-GFER/ERV1 disulfide relay system. The
CC formation of 2 disulfide bonds in the Cx2C motifs through
CC dithiol/disulfide exchange reactions effectively traps the protein in
CC the mitochondrial intermembrane space. {ECO:0000255|HAMAP-
CC Rule:MF_03115}.
CC -!- DOMAIN: The C-terminal domain binds 2 Fe-S clusters but is otherwise
CC mostly in an intrinsically disordered conformation. {ECO:0000255|HAMAP-
CC Rule:MF_03115}.
CC -!- DOMAIN: The N-terminal domain has structural similarity with S-
CC adenosyl-L-methionine-dependent methyltransferases, but does not bind
CC S-adenosyl-L-methionine. It is required for correct assembly of the 2
CC Fe-S clusters. {ECO:0000255|HAMAP-Rule:MF_03115}.
CC -!- SIMILARITY: Belongs to the anamorsin family. {ECO:0000255|HAMAP-
CC Rule:MF_03115}.
