Description of Recombinant Human PTPRN, N-His

Introduction to Recombinant Human PTPRN

Recombinant Human PTPRN, also known as protein tyrosine phosphatase receptor type N, is a recombinant protein that has been produced through genetic engineering techniques. This protein plays a crucial role in regulating cellular signaling pathways by dephosphorylating tyrosine residues on target proteins. It is a member of the protein tyrosine phosphatase (PTP) family and is highly expressed in the brain, pancreas, and liver.

Structure of Recombinant Human PTPRN

Recombinant Human PTPRN is a 923 amino acid protein with a molecular weight of approximately 105 kDa. It consists of a single catalytic domain, a transmembrane domain, and a cytoplasmic domain. The catalytic domain contains a conserved cysteine residue that is essential for its phosphatase activity. The transmembrane domain anchors the protein to the cell membrane, while the cytoplasmic domain contains regulatory motifs that control its activity.

Activity of Recombinant Human PTPRN

Recombinant Human PTPRN is a phosphatase enzyme that specifically dephosphorylates tyrosine residues on target proteins. It plays a crucial role in regulating various cellular processes such as cell growth, differentiation, and survival.
