this is the family of proteins that regulates cell cycle progression

this is CDK

this interacts with cyclin CDK complex to inhibit kinase activity

this is the two main groups of cyclin

this is happen only when complexed with cyclins, kinase is activated.

this are group of transcription factors that participate in cell cycle and DNA synthesis

this is where cyclin D primarily works at

this can be modulated upon binding with cyclin

this is the group of activators that are inhibited

this is where cyclin E primarily works at

this is CDK activating kinase on T-loop

this is where cell cycle is controlled

this is where cyclin A primarily works at

this is to ensure the correct progression of cell cycles after entry to new phases

these are 3 major checkpoints
