The CDKN2AIPNL gene is located on chromosome 5 and encodes a protein that is predicted to be active in the nucleolus and nucleoplasm . The human recombinant form of this protein is produced in E. coli and consists of a single polypeptide chain containing 139 amino acids, with a molecular mass of approximately 15.6 kDa .
CDKN2AIPNL is involved in the regulation of the cell cycle, particularly through its interaction with the CDKN2A gene. The CDKN2A gene encodes several transcript variants that function as inhibitors of CDK4 kinase, a crucial regulator of cell cycle G1 progression . By interacting with CDKN2A, CDKN2AIPNL may play a role in stabilizing the tumor suppressor protein p53, which is essential for preventing uncontrolled cell proliferation and tumor development .
Given its interaction with the CDKN2A gene, CDKN2AIPNL is of interest in cancer research. The CDKN2A gene is frequently mutated or deleted in a wide variety of tumors, making it a critical target for understanding cancer development and progression . The study of CDKN2AIPNL and its recombinant forms could provide valuable insights into the mechanisms of tumor suppression and potential therapeutic strategies.
The human recombinant form of CDKN2AIPNL is produced using E. coli expression systems. The recombinant protein includes a 23 amino acid His-tag at the N-terminus, which facilitates its purification through chromatographic techniques . This recombinant protein is used in various research applications to study its function and interactions in a controlled environment.
