Anti-KPI-2 antibodies enable researchers to detect and measure the KPI-2 antigen in biological samples. This target is a reported synonym of the LMTK2 gene, which encodes lemur tyrosine kinase 2. This protein is known to function in peptidyl-serine phosphorylation and protein phosphorylation, among other biological roles. The human version of KPI-2 has a canonical amino acid length of 1503 residues and a protein mass of 164.9 kilodaltons. It is reported to be localized in the membrane of cells. KPI-2 is a member of the Tyr protein kinase protein family.
