  12. The protein level of p21 increased lightly from 1 to3 h, then decreased at 6 - 9 h, reached maximum at 24 h after 2gy, it increased from 3 to 24 h exposed tology, and the protein level of p21 associated with cdk2 increased, which did not inhibit the cyclin e / cdk2 kinase activity, because of upregulation of cyclin e and deregulation of p27kipl after irradiation. in contrast to p21, p27kipl may be a key regulator of cyclin e / cdk2 activity in dna damage responses. hi the ubiquitin - proteasome pathway invovled in regulation of p27kiplexpression in response to ir the ubiquitin - proteasome pathway regulated selective and time - controlled elimination of p27 kipl
