Table 1: Known CDKs, their cyclin partners, and their functions in the human and consequences of deletion in mice.
| CDK | Cyclin partner | Function | Deletion Phenotype in Mice |
|---|---|---|---|
| Cdk1 | Cyclin B | M phase | None. ~E2.5. |
| Cdk2 | Cyclin E | G1/S transition | Reduced size, imparted neural progenitor cell proliferation. Viable, but both males & females sterile. |
| Cdk2 | Cyclin A | S phase, G2 phase | |
| Cdk3 | Cyclin C | G1 phase ? | No defects. Viable, fertile. |
| Cdk4 | Cyclin D | G1 phase | Reduced size, insulin deficient diabetes. Viable, but both male & female infertile. |
| Cdk5 | p35 | Transcription | Severe neurological defects. Died immediately after birth. |
| Cdk6 | Cyclin D | G1 phase | |
| Cdk7 | Cyclin H | CDK-activating kinase, transcription | |
| Cdk8 | Cyclin C | Transcription | |
| Cdk9 | Cyclin T | Transcription | Embryonic lethal |
| Cdk11 | Cyclin L | ? | Mitotic defects. E3.5. |
| ? | Cyclin F | ? | Defects in extraembryonic tissues. E10.5. |
| ? | Cyclin G | ? |

Famous quotes containing the word types:
“He’s one of those know-it-all types that, if you flatter the wig off him, he chatter like a goony bird at mating time.”
—Michael Blankfort. Lewis Milestone. Johnson (Reginald Gardner)
“... there are two types of happiness and I have chosen that of the murderers. For I am happy. There was a time when I thought I had reached the limit of distress. Beyond that limit, there is a sterile and magnificent happiness.”
—Albert Camus (1913–1960)
“Our children evaluate themselves based on the opinions we have of them. When we use harsh words, biting comments, and a sarcastic tone of voice, we plant the seeds of self-doubt in their developing minds.... Children who receive a steady diet of these types of messages end up feeling powerless, inadequate, and unimportant. They start to believe that they are bad, and that they can never do enough.”
—Stephanie Martson (20th century)
