Comments concerning this interaction

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

(Huang et al., 2013)

The N-terminal par-1 region, containing the kinase domain, binds hpo far more strongly than the full length par-1 protein.

(Huang et al., 2013)

Co-transfection of par-1 and hpo induces phosphorylation of hpo at Ser30 and inhibits phosphorylation of hpo at Thr195.
