Peptide T is an octapeptide from the V2 region of HIV-1 gp120. This synthetic octapeptide potentially functions through competitive inhibition of gp120 binding to the CD4 receptor, as well as interaction with vasointestinal peptide (VIP) receptors.
Endogenous peptide product of human prepro-VIP and analog of porcine PHI-27; potent agonist for the human calcitonin receptor (EC50 = 11 nM). Transgenic mice expressing the human VIP/PHM 27 gene in pancreatic β-islets display enhanced glucose-induced insu
