human_protein_name: peptidyl-prolyl cis-trans isomerase B precursor
description: Macrophage- and T-cell-tropic V3 loop peptides of HIV-1 gp120 bind specifically to the active site of the immunophilins FK506-binding protein (FKBP12), and cyclophilins A and B, and inhibit their peptidyl-prolyl cis-trans isomerase (PPIase) activities
