- The correct title of this article is p21. The initial letter is shown capitalized due to technical restrictions.
p21, also known as cyclin-dependent kinase inhibitor 1A or CDKN1A, is a human gene on chromosome 6 (location 6p21.2), that encodes a cyclin-dependent kinase inhibitor that directly inhibits the activity of cyclin-CDK2 and cyclin-CDK4 complexes. p21 functions as a regulator of cell cycle progression at G1 phase[1]. The expression of p21 is controlled by the tumor suppressor protein p53.
The function of this gene relates in part to stress response [2].
