Comments concerning this interaction

Two-hybrid system: yeast LexA-BD/B42-AD

(Lorenzen et al., 2001)

30% of csw-interacting clones represented msk cDNAs.

(Lorenzen et al., 2001)

Source was yeast cell line; bait produced as transgenic fusion protein; prey produced as transgenic fusion protein (prey from ovary cDNA expression library).
