Description

Amino Acid Sequence

Trp-Lys-Tyr-Met-Val-L-Met NH2

Application

WKYMVM trifluoroacetate salt was used as a test compound for investigating the mechanism of regulation of lipoprotein-associated phospholipase A2 (Lp-PLA2).

Actions biochimiques/physiologiques

WKYMVM is a peptide agonist of formyl peptide receptors.

WKYMVM is a peptide agonist of formyl peptide receptors. WKYMVM binds to and stimulates FPRL family members 1, 2 with EC50 values of 2 and 80 nM, respectively. The peptide is a potent activator of neutrophils.

WKYMVM is an agonist and potent activator of Formyl peptide receptor like-1 (FPRL1). WKYMVM stimulates FPRL1 and hence attenuates the function of the chemokine receptors CCR5 and CXCR4. WKYMVM activates human eosinophils to induce superoxide production through Phosphoinositide 3-Kinase-Mediated ERK1/2 pathway.

Notes préparatoires

WKYMVM trifluoroacetate salt dissolves in water at a concentration >2 mg/mL to yield a clear solution.
