INK4 is a family of cyclin-dependent kinase inhibitors. The members of this family are inhibitors of CDK4, and of CDK6. The other family of CKIs, CIP/KIP proteins are capable of inhibiting all CDKs. E
INK4 in cyclin/CDK pathway
The cell cycle, or cell-division cycle, is the sequence of events that take place in a cell and lead to its division into two daughter cells. These events include the growth of the cell, duplication o

…resassortment of Cip/Kip proteins between CDK4/5 and CDK2 as cells progress through G1. Their function, inhibiting CDK4/6, is to block progression of the cell cycle beyond the G1 restriction point. In addition, INK4 proteins play roles in cellular senescence, apoptosis and DNA repair. INK4 proteins are tumor…
Onion (Allium) cells in different phases of the cell cycle. Growth of the organism is carefully controlled by regulating the cell cycle.
Cytokinesis in animal cells and plant cells
Overview of the cell cycle checkpoints, visual reference of what it does and where it happens.
Overviews of the G1/S transition control networks in plants, animals, and yeast. All three show striking network topology similarities, even though individual proteins in the network have very little sequence similarity.
