Comments concerning this interaction

Source was cell extract of Kc cell line; bait produced from transfected construct; prey produced from transfected construct.

drl and Src64B specifically co-immunoprecipitate in the presence or absence of Wnt5 protein. Src64B tyrosine kinase activity is required for the formation and stability of the drl-Src64B complex.
