H-Met-Ala-Gly-Pro-His-Pro-Val-Ile-Val-Ile-Thr-Gly-Pro-His-Glu-Glu-OH Structural

What is H-Met-Ala-Gly-Pro-His-Pro-Val-Ile-Val-Ile-Thr-Gly-Pro-His-Glu-Glu-OH?

Description

NFAT inhibitor is a cell-permeable compound that selectively inhibits calcineurin-mediated dephosphorylation of NFAT. At 100 μM, this inhibitor effectively blocks calcineurin binding to NFAT without disrupting other calcineurin-dependent pathways, unlike the immunosuppressants cyclosporin A and FK506 which indiscriminately block all calcineurin phosphatase activity. NFAT inhibitor can disrupt NFAT-dependent expression of IL-2 and TNF-α when transfected in Jurak T cells and can prevent the activation and proliferation of T cells both in vitro (~ 43% at 1 μM using mixed lymphocyte cultures) and in vivo (10 mg/kg using C3H/HeN mice).

The Uses of H-Met-Ala-Gly-Pro-His-Pro-Val-Ile-Val-Ile-Thr-Gly-Pro-His-Glu-Glu-OH

NFAT Inhibitor, VIVIT has been used to study the signaling pathways involved in controlling inhibitory molecules and subsequent onset of T-cell impairment.

Biochem/physiol Actions

High-affinity calcineurin-binding peptide that inhibits NFAT (Nuclear Factor of Activated T cells) activation and NFAT-dependent expression of endogenous cytokine genes in T cells.
