Anti-C13orf22 antibodies enable researchers to detect and measure the C13orf22 antigen in biological samples. This target is a reported synonym of the USPL1 gene, which encodes ubiquitin specific peptidase like 1. This protein is known to function in cell proliferation, among other biological roles. The human version of C13orf22 has a canonical amino acid length of 1092 residues and a protein mass of 120.4 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus of cells. C13orf22 is a member of the Peptidase C19 protein family.
