General description
PTPRF or leukocyte common antigen-related protein (LAR) is a widely expressed protein tyrosine phosphatase with an extracellular receptor region that resembles a cell adhesion molecule.
Protein tyrosine phosphatase, receptor type F (PTPRF) consists of noncovalently bound subunits designated as E (extracellular) and P (phosphatase) subunits that are derived from a precursor protein by proteolytic processing. The E subunit (150 kDa) has three immunoglobulin-like domains and eight fibronectin III-like domains, and the P subunit (85 kDa) has a short extracellular domain, a transmembrane segment and tandem cytoplasmic PTP catalytic domains.
Specificity
The antibody recognizes both the extracellular and the cytoplasmic subunits of human PTPRF. Anti-PTPRF (C-terminal) antibody is specific for the P- subunit and the whole PTPRF protein from Human origin. Detection of the PTPRF bands by immunoblotting is specifically inhibited by the immunizing peptide.
Application
Anti-PTPRF (C-terminal) antibody produced in rabbit has been used in an enzyme based assay of protein tyrosine phosphatase 1 (PTP1).
The antibody may be used in several immunochemical techniques including immunoblotting (∼210, ∼150, and ∼85 kDa) and immunoprecipitation.
Biochem/physiol Actions
Protein tyrosine phosphatase, receptor type F (PTPRF) removes phosphate group from β-catenin, an event that may subsequently facilitate cell-cell adhesion and ensure the stability of the cadherin complex. This phosphatase has also been implicated in various cellular processes such as neurite growth, nerve regeneration, actin remodeling and regulation of insulin function. Insulin receptor, epidermal growth factor receptor (EGF) receptor, hepatocyte growth factor (HGF) receptor and rearranged during transfection (RET) have been reported as substrates of PTPRF.

The protein tyrosine phosphatases (PTPs) have emerged as critical players in diverse cellular functions. The focus of this review is the leukocyte common antigen-related (LAR) subfamily of receptor PTPs (RPTPs). This subfamily is composed of three vertebrate homologs, LAR, RPTP-sigma

The leukocyte common antigen-related protein, LAR, is a receptor-like protein tyrosine phosphatase (PTP) which has a wide tissue distribution. Post-translational processing cleaves the proprotein into two non-covalently associated subunits, an extracellular subunit resembling a cell adhesion molecule with three immunoglobulin-like

The vascular barrier that separates blood from tissues is actively regulated by the endothelium and is essential for transport, inflammation, and haemostasis. Haemodynamic shear stress plays a critical role in maintaining endothelial barrier function, but how this occurs remains unknown.
