HsRad51, or RAD51 recombinase, is a human gene encoded by RAD51. It may also be known as: DNA repair protein RAD51 homolog 1; hRAD51; RAD51 homolog A; HsRAD51; BRCA1/BRCA2-containing complex, subunit 5; BRCC5; HsT16930; MRMV2; RAD51A; RECA. The encoded protein has an amino acid length of 339 and a mass of 37.0 kDa. Other isoforms may exist. HsRad51 is a member of the RecA family, RAD51 subfamily. Homologs of this gene exist in other organisms, including: Mouse, E. coli, Frog.
