== Function ==
[https://www.uniprot.org/uniprot/CIA2A_HUMAN CIA2A_HUMAN] Component of the cytosolic iron-sulfur protein assembly (CIA) complex, a multiprotein complex that mediates the incorporation of iron-sulfur cluster into extramitochondrial Fe/S proteins (PubMed:23891004). As a CIA complex component and in collaboration with CIAO1 specifically matures ACO1 and stabilizes IREB2, connecting cytosolic iron-sulfur protein maturation with cellular iron regulation (PubMed:23891004). May play a role in chromosome segregation through establishment of sister chromatid cohesion. May induce apoptosis in collaboration with APAF1 (PubMed:25716227).<ref>PMID:23891004</ref> <ref>PMID:25716227</ref>

== Publication Abstract from PubMed ==
Fam96a mRNA, which encodes a mammalian DUF59 protein, is enriched in macrophages. Recombinant human Fam96a forms stable monomers and dimers in solution. Crystal structures of these two forms revealed that each adopts a distinct type of domain-swapped dimer, one of which is stabilized by zinc binding. Two hinge loops control Fam96a domain swapping; both are flexible and highly conserved, suggesting that domain swapping may be a common feature of eukaryotic but not bacterial DUF59 proteins. The derived monomer fold of Fam96a diverges from that of bacterial DUF59 counterparts in that the C-terminal region of Fam96a is much longer and is positioned on the opposite side of the N-terminal core fold. The putative metal-binding site of bacterial DUF59 proteins is not conserved in Fam96a, but Fam96a interacts tightly in vitro with Ciao1, the cytosolic iron-assembly protein. Moreover, Fam96a and Ciao1 can be co-immunoprecipitated, suggesting that the interaction also occurs in vivo. Although predicted to have a signal peptide, it is shown that Fam96a is cytoplasmic. The data reveal that eukaryotic DUF59 proteins share intriguing characteristics with amyloidogenic proteins.
