Anti-KPL1 antibodies enable researchers to detect and measure the KPL1 antigen in biological samples. This target is a reported synonym of the PLEKHB1 gene, which encodes pleckstrin homology domain containing B1. This protein is known to function in the regulation of cell differentiation, among other biological roles. The human version of KPL1 has a canonical amino acid length of 243 residues and a protein mass of 27.2 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the membrane and cytoplasm of cells.
