Comments concerning this interaction

Sfmbt coimmunoprecipitates pho, Rpd3, HP1b, Nap1 and ocm in three independent purifications: the PhoRC-L complex.

(Alfieri et al., 2013)

Source was embryonic nuclear extract of transgenic fly line; bait produced from tagged transgenic construct; prey produced from endogenous gene.
