      Entrez Gene Number
      Entrez Gene SummaryThis gene encodes a potent cyclin-dependent kinase inhibitor. The encoded protein binds to and inhibits the activity of cyclin-CDK2 or -CDK4 complexes, and thus functions as a regulator of cell cycle progression at G1. The expression of this gene is tightly controlled by the tumor suppressor protein p53, through which this protein mediates the p53-dependent cell cycle G1 phase arrest in response to a variety of stress stimuli. This protein can interact with proliferating cell nuclear antigen (PCNA), a DNA polymerase accessory factor, and plays a regulatory role in S phase DNA replication and DNA damage repair. This protein was reported to be specifically cleaved by CASP3-like caspases, which thus leads to a dramatic activation of CDK2, and may be instrumental in the execution of apoptosis following caspase activation. Two alternatively spliced variants, which encode an identical protein, have been reported.

      UniProt Number
      UniProt SummaryFUNCTION: SwissProt: P38936 # May be the important intermediate by which p53 mediates its role as an inhibitor 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.
      SIZE: 164 amino acids; 18119 Da
      SUBCELLULAR LOCATION: Cytoplasm. Nucleus.
      TISSUE SPECIFICITY: Expressed in all adult human tissues, with 5- fold lower levels observed in the brain.
      PTM: Phosphorylation of Thr-145 by Akt or of Ser-146 by PKC impairs binding to PCNA.
      SIMILARITY: SwissProt: P38936 ## Belongs to the CDI family.
