Protein tyrosine phosphatase (PTP) substrate

Ref. 3D-CRB1000745

Product Information

• Name: Protein tyrosine phosphatase (PTP) substrate
• Synonyms: H-END(pY)INASL-OH
• Brand: Biosynth
• Description: The sequence of this peptide has been derived from a highly conserved region of the T-cell phosphatase TC.PTP45 and is an excellent general substrate for protein tyrosine phosphatases.The protein tyrosine phosphatase (PTP) superfamily has 103 enzymes that catalyse substrate dephosphorylation at tyrosine residues through a covalent enzyme intermediate involving a thiophosphate linkage from the active site cysteine residue. All PTPs share a common signature motif (I/V)HCXAGXGR(S/T), named the P-loop, responsible for the enzyme activity. The PTP superfamily can be divided into four classes based on their cellular localization/catalytic domains: the receptor-like PTPs (rPTPs), the non-receptor PTPs (nrPTPs), the low molecular weight PTP (LMWPTP), and the VH-1 and CDC-25 groups.PTPs are involved in regulating a plethora of cellular activities, including proliferation and differentiation, survival, migration, metabolism, and the immune response. Abnormal protein tyrosine phosphorylation has been associated with the etiology of various human diseases, including cancer, diabetes, and autoimmune dysfunctions, therefore making PTPs novel therapeutic targets.
