WebCyclins are a group of proteins, which control progression of cell cycle by activating group of cyclin dependent kinase enzymes (CDKs). Cyclins and CDKs together coordinate to synthesize enzymes and proteins required for cell cycle. After the function is performed, the cyclins are degraded leaving the CDKs inactive and non-functional. WebJan 4, 2024 · Abstract. The class I cyclin family is a well-studied group of structurally conserved proteins that interact with their associated cyclin-dependent kinases (Cdks) to regulate different stages of cell cycle progression depending on their oscillating expression levels. However, the role of class II cyclins, which primarily act as transcription ...
