The present results thus show that p70(s6k) is able to regulate E2F transcriptional activity and provide direct evidence for the first time for a link between IL-2 receptors, PI 3-kinase , and p70(s6k) that regulates a crucial G1 checkpoint in T lymphocytes .
 ( cell type: T lymphocytes, None) , ( protein: p70(s6k), None) , ( protein: E2F, None) , ( protein: PI 3-kinase, None) , ( protein: IL-2, None) , ( protein: p70(s6k), None)
