Anti-Ankyrin repeat domain 32 antibodies are used in antigen-specific immunodetection in biological samples. The target Ankyrin repeat domain 32 is a known alias name of the protein SMC5-SMC6 complex localization factor 1, encoded by the SLF1 gene in humans. This 1058-amino acid residue protein is reported to play a role in the DNA damage response (DDR) pathway by regulating postreplication repair of UV-damaged DNA and genomic stability maintenance. It is localized to the nucleus and cytoplasm of the cell. Other synonyms for Ankyrin repeat domain 32 include SMC5-SMC6 complex localization factor protein 1, BRCT domain containing 1, and BRCT domain-containing protein 1.
