WL47 

Cat. No.: HY-P2288
Handling Instructions

WL47, a high-affinity cavolin-1 (CAV1) ligand (Kd=23 nM), is a potent disrupter of CAV1 oligomers. WL47 shows selectivity for CAV1 over BSA, casein and HEWL. WL47 is 80% smaller in length than the original T20 (HY-P0052) parent sequence and can be used for the study of caveolin-1 function.

Description

WL47, a high-affinity cavolin-1 (CAV1) ligand (Kd=23 nM), is a potent disrupter of CAV1 oligomers. WL47 shows selectivity for CAV1 over BSA, casein and HEWL. WL47 is 80% smaller in length than the original T20 (HY-P0052) parent sequence and can be used for the study of caveolin-1 function[1].

In Vitro

Caveolin-1 (CAV) is a monotonic membrane protein, 22 kDa, it penetrates only one leaflet of the lipid bilayer, and both the N- and C-termini remain on the cytoplasmic side. Multiple copies of CAV oligomerize can form high molecular weight complexes that bend the membrane inward to form invaginations, termed “caveolae,” of 50-100 nm in diameter.
T20 is a 36 amino acid peptide derived from gp41 and blocks HIV viral fusion with CD4+ T-cells. WL47 is 80% smaller in length and has 7500-fold greater affinity than the original T20 parent sequence.
In vitro, Demonstrating WL47 activity with CAV oligomers and a method for measuring the degree of oligomerization. A variant of CAV (CAV(FLV)) that spontaneously oligomerizes to form CAV nanoparticles with diameters is used to examine deoligomerization by WL47. WL47 effectively disrupts these nanoparticles, but it does not disrupt oligomerization in the presence of a reducing agent, this demonstating that WL47 function requires dimerization by disulfide bond.

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
