Introduction
Recombinant Human PTPRQ Protein is a protein that is produced through genetic engineering techniques, where specific DNA sequences are inserted into host cells to produce a desired protein. PTPRQ stands for Protein Tyrosine Phosphatase, Receptor Type Q, and it is a member of the protein tyrosine phosphatase (PTP) family. This protein plays a crucial role in various cellular processes and has been extensively studied for its structure, activity, and potential applications.
Structure of Recombinant Human PTPRQ Protein
Recombinant Human PTPRQ Protein is composed of 1111 amino acids and has a molecular weight of approximately 125 kDa. It consists of a single transmembrane domain, a cytoplasmic domain, and an extracellular domain. The extracellular domain contains multiple fibronectin type III repeats, which are involved in protein-protein interactions. The cytoplasmic domain contains two catalytic domains, D1 and D2, which are responsible for the phosphatase activity of the protein.
Activity of Recombinant Human PTPRQ Protein
The main function of Recombinant Human PTPRQ Protein is to dephosphorylate tyrosine residues on target proteins. This activity is crucial for regulating various cellular processes, such as cell growth, differentiation, and signaling. PTPRQ has been shown to interact with multiple proteins, including growth factor receptors, ion channels, and cytoskeletal proteins, through its extracellular and cytoplasmic domains. By dephosphorylating these proteins, PTPRQ can modulate their activity and affect downstream signaling pathways.
In addition to its phosphatase activity, Recombinant Human PTPRQ Protein has also been found to have adhesive properties. The fibronectin type III repeats in the extracellular domain play a role in cell-cell and cell-matrix interactions. This adhesive function may contribute to the protein’s role in cell adhesion and migration, which are essential processes in tissue development and repair.
