General description
PTPRF or LAR is a member of the protein tyrosine phosphatase family with an extracellular region, a single transmembrane region, and two tandem intracytoplasmic catalytic domains. PTPRF has been shown to function in the regulation of epithelial cell-cell contacts at adherents junctions as well as in the control of beta-catenin signaling. An increased expression level of this protein was found in the insulin-responsive tissue of obese, insulin-resistant individuals, and may contribute to the pathogenesis of insulin resistance.

Most receptor-like, transmembrane protein tyrosine phosphatases (PTPases), such as CD45 and the leukocyte common antigen-related (LAR) molecule, have two tandemly repeated PTPase domains in the cytoplasmic segment. The role of each PTPase domain in mediating PTPase activity remains unclear; however

The receptor-type protein-tyrosine phosphatase LAR (for leukocyte common antigen-related) has been implicated as a physiological regulator of the insulin receptor. To demonstrate a functional interaction between LAR and the insulin receptor, we incubated CHO cells overexpressing the human insulin receptor
