WebFeb 12, 2008 · Second, like p57, p21 can bind to JNK kinases through its cyclin-CDK binding domain, which both inhibits JNK activity and prevents JNK activation by upstream kinases ( Shim et al., 1996 ). So far, there have not been any reports to suggest that p27 can directly interfere with pro- or antiapoptotic pathways. WebJan 17, 2014 · Expression of p21 (Cip1) and p27 (Kip1) but not p57 (Kip2) showed a peak around postnatal day 5, when cyclin E- and cyclin A-CDK activities start to decrease. p21 (Cip1) and p27 (Kip1) bound to cyclin E, cyclin A and CDK2 at postnatal stages.
