Descrição geral

Cyclin dependent kinase inhibitor 2A (CDKN2A) also known as p16-INK-4a, belongs to the Ink4 (inhibitor of CDK4) family of CDK inhibitors. It is encoded by the gene mapped to human chromosome 9p21 within the INK4a/ alternate reading frame (ARF) locus. Human P16-INK4A is localized in both nucleus and cytoplasm, and its expression increases with ageing in skin and kidney tissues.

Ações bioquímicas/fisiológicas

Cyclin dependent kinase inhibitor 2A (CDKN2A), also known as p16-INK-4a, arrests cell cycle progression by inhibiting S-phase and promotes apoptosis. The encoded protein has anti-proliferative biological activity, and is implicated in the retinoblastoma (Rb) protein pathway. p16-INK-4a acts as a tumor suppressor and plays a vital role in ageing and cellular senescence. Increased expression of this protein might lead to various types of high grade cancers. p16-INK-4a also facilitates cell invasion and angiogenesis. Bronchial lavage P16INK4A promoter methylation might function as a potential biomarker for diagnosis of lung cancer.

Reconstituição

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.

Stem cells persist throughout life in diverse tissues by undergoing self-renewing divisions. Self-renewal capacity declines with age, partly because of increasing expression of the tumor suppressor p16(Ink4a).
