Comments concerning this interaction

Source was cell extract of S2 cell line; bait produced from transfected construct; prey produced from transfected construct.

Uses sevS11 allele, a constitutively activated form that consists of the C-terminal Sev protein, which includes the intracellular tyrosine kinase domain, bound to the signal peptide of the Drosophila cuticle protein CP3 and the 10 amino acid Myc epitope.

Comments concerning this interaction

Source was live S2 cells; proteins produced from transfected constructs.

Uses sevS11 allele, a constitutively activated form that consists of the C-terminal Sev protein, which includes the intracellular tyrosine kinase domain, bound to the signal peptide of the Drosophila cuticle protein CP3 and the 10 amino acid Myc epitope.
