Anti-PPP1R40 antibodies enable researchers to detect and measure the PPP1R40 antigen in biological samples. This target is a reported synonym of the TRIM42 gene, which encodes tripartite motif containing 42. The human version of PPP1R40 has a canonical amino acid length of 723 residues and a protein mass of 82.7 kilodaltons, although 2 isoforms have been identified. PPP1R40 is a member of the TRIM/RBCC protein family.
