squarunkinA

Selective inhibitor of the interaction between the UNC119 chaperone and its cargo. Squarunkin A inhibits activation of Src kinase by interrupting the interaction between the myristoylated peptide at the N-terminus of the Src kinase and UNC119A chaperone (IC50 = 10 nM). Squarunkin A impairs the UNC119-mediated enrichment of plasma membrane with non-receptor protein tyrosine kinase Src, resulting in the decrease in Src autophosphorylation and decreased oncogenic Src signalling.

squarunkinA is a novel modulator of the UNC119-Cargo Interaction, potently and selectively inhibiting the binding of a myristoylated peptide representing the N-
