Anti-DDK1 antibodies enable researchers to detect and measure the DDK1 antigen in biological samples. This target is a reported synonym of the MGME1 gene, which encodes mitochondrial genome maintenance exonuclease 1. This protein is known to function in DNA replication, among other biological roles. The human version of DDK1 has a canonical amino acid length of 344 residues and a protein mass of 39.4 kilodaltons. It is reported to be localized in the mitochondria of cells and widely expressed in many tissue types. DDK1 is a member of the MGME1 protein family.
