Human Protein Tyrosine Phosphatase Receptor Type J (PTPRJ) CLIA Kit

Human Protein Tyrosine Phosphatase Receptor Type J (PTPRJ) CLIA Kit is a Sandwich CLIA Kit for use with Tissue homogenates, cell lysates and other biological fluids.

Background

Protein tyrosine phosphatase receptor type J (PTPRJ) is a transmembrane protein belonging to the protein tyrosine phosphatase family, which regulates cellular signaling pathways by dephosphorylating tyrosine residues on target proteins this receptor-like phosphatase is broadly expressed in various tissues including endothelial cells, immune cells, and epithelial cells and is implicated in controlling cell growth, adhesion, and migration it negatively regulates key signaling pathways such as those mediated by receptor tyrosine kinases including VEGFR, PDGFR, and EGFR, making it a critical player in angiogenesis, immune responses, and tumor suppression its reduced expression or functional inactivation has been associated with several cancers, including colorectal, thyroid, and breast cancers, where its loss promotes tumor progression and metastasis emerging studies suggest its role in modulating the immune microenvironment and its potential as a therapeutic target to enhance immune checkpoint therapies ongoing research focuses on elucidating its broader functions in cellular homeostasis and its utility in precision medicine.
