Anti-PP1628 antibodies enable researchers to detect and measure the PP1628 antigen in biological samples. This target is a reported synonym of the PLEKHO2 gene, which encodes pleckstrin homology domain containing O2. The human version of PP1628 has a canonical amino acid length of 490 residues and a protein mass of 53.4 kilodaltons, although 2 isoforms have been identified. It is reported to be notably expressed in many tissues, such as the bone marrow, tonsil, and adrenal gland.
