MSH: A large family of regulatory proteins that function as accessory subunits to a variety of CYCLIN-DEPENDENT KINASES. They generally function as ENZYME ACTIVATORS that drive the CELL CYCLE through transitions between phases. A subset of cyclins may also function as transcriptional regulators.,CSP: family of proteins which accumulate during interphase of the eukaryotic cell cycle and are destroyed at the conclusion of mitosis; believed to be involved in inducing mitosis.,NCI: A non-enzymatic regulatory protein that is critical during the cell cycle. The cyclin family members complex with other proteins to modulate the protein kinase activity of the cell.
