CDKN1A

Universal Cellular Machinery · Cell Cycle Control & Mitotic Division

How does a cell pause division after DNA damage?

CDKN1A makes p21, which inhibits enzymes that move the cell cycle forward. This helps implement a pause in response to signals such as those from p53.

Common Gene Name: cyclin dependent kinase inhibitor 1A
NCBI Gene ID: 1026
Chromosome: 6
