CDKN1A (Cyclin Dependent Kinase Inhibitor 1A) is a Protein Coding gene. Diseases associated with CDKN1A include Multiple Endocrine Neoplasia, Type I and Tongue Carcinoma. Among its related pathways are Cellular Senescence and Defective binding of RB1 mutants to E2F1, (E2F2, E2F3). Gene Ontology (GO) annotations related to this gene include ubiquitin protein ligase binding and cyclin binding. An important paralog of this gene is CDKN1C. The gene discussed is E2F3; the disease is multiple endocrine neoplasia.
