Q96T76

Target Species

Human

Target Name

MMS19

Target Full Name

MMS19 nucleotide excision repair protein homolog

Target Function

Key component of the cytosolic iron-sulfur protein assembly (CIA) complex, a multiprotein complex that mediates the incorporation of iron-sulfur cluster into apoproteins specifically involved in DNA metabolism and genomic integrity. In the CIA complex, MMS19 acts as an adapter between early-acting CIA components and a subset of cellular target iron-sulfur proteins such as ERCC2/XPD, FANCJ and RTEL1, thereby playing a key role in nucleotide excision repair (NER), homologous recombination-mediated double-strand break DNA repair, DNA replication and RNA polymerase II (POL II) transcription. As part of the mitotic spindle-associated MMXD complex, plays a role in chromosome segregation, probably by facilitating iron-sulfur (Fe-S) cluster assembly into ERCC2/XPD. Together with CIAO2, facilitates the transfer of Fe-S clusters to the motor protein KIF4A, which ensures proper localization of KIF4A to mitotic machinery components to promote the progression of mitosis. Indirectly acts as a transcriptional coactivator of estrogen receptor (ER), via its role in iron-sulfur insertion into some component of the TFIIH-machinery.

Target Background

Enables estrogen receptor binding activity and transcription coactivator activity. Involved in several processes, including iron-sulfur cluster assembly; positive regulation of nucleobase-containing compound metabolic process; and protein maturation by iron-sulfur cluster transfer. Located in cytosol; nucleoplasm; and spindle. Part of CIA complex and MMXD complex.
