---|---|---|
UniProt AC | P38936 | |
Protein Name | Cyclin-dependent kinase inhibitor 1 | |
Gene Name | CDKN1A | |
Organism | Homo sapiens (Human). | |
Sequence Length | 164 | |
Subcellular Localization | Cytoplasm. Nucleus. | |
Protein Description | May be involved in p53/TP53 mediated inhibition of cellular proliferation in response to DNA damage. Binds to and inhibits cyclin-dependent kinase activity, preventing phosphorylation of critical cyclin-dependent kinase substrates and blocking cell cycle progression. Functions in the nuclear localization and assembly of cyclin D-CDK4 complex and promotes its kinase activity towards RB1. At higher stoichiometric ratios, inhibits the kinase activity of the cyclin D-CDK4 complex. Inhibits DNA synthesis by DNA polymerase delta by competing with POLD3 for PCNA binding.
