The morphogenesis checkpoint in Saccharomyces cerevisiae: cell cycle control of Swe1p degradation by Hsl1p and Hsl7p.

abstract：:Transforming growth factor beta (TGF-beta) plays important roles in the regulation of proliferation, differentiation, apoptosis, and carcinogenesis. To identify genes responsible for maintaining the phenotype induced by TGF-beta, we performed a retrovirus-mediated gene trap screening designed to isolate TGF-beta-respo...
