HIV-1 TAT PROTEIN DERIVED N-TERMINAL NONAPEPTIDE TRP2-TAT (1-9) BOUND TO THE ACTIVE SITE OF DIPEPTIDYL PEPTIDASE IV (CD26)
OverviewOverview
CD26 or dipeptidyl-peptidase IV (DPPIV) is engaged in immune functions by, co-stimulatory effects on activation and proliferation of T lymphocytes, binding to adenosine deaminase, and regulation of various chemokines and, cytokines. DPPIV peptidase activity is inhibited by both Tat protein from, human immunodeficiency virus (HIV)-1 and its N-terminal nonapeptide, Tat-(1-9) with amino acid sequence MDPVDPNIE, suggesting that DPPIV, mediates immunosuppressive effects of Tat protein. The 2.0- and 3.15-A, resolution crystal structures of the binary complex between human DPPIV, and nonapeptide Tat-(1-9) and the ternary complex between the variant, MWPVDPNIE, called Trp(2)-Tat-(1-9), and DPPIV bound to adenosine deaminase, show that Tat-(1-9) and Trp(2)-Tat-(1-9) are located in the active site ...
