Identification of a zinc finger protein whose subcellular distribution is regulated by serum and nerve growth factor.

abstract：:Cell cycle progression is tightly regulated by cyclin-dependent kinases (CDKs). The ankyrin-repeat protein p19INK4d functions as a key regulator of G1/S transition; however, its molecular mode of action is unknown. Here, we combine cell and structural biology methods to unravel the mechanism by which p19INK4d controls...
