Weitere Details:: The Ink4a-Arf locus encodes two tumor suppressor proteins, p16Ink4a and p19Arf. Expression of Ink4a and Arf is regulated by distinct promoters upstream of alternative first exons whose products are spliced to a common second exon translated in alternative reading frames (from which Arf gets its name). The two genes are induced by different stress signals and can be separately mutated or silenced in tumor cells. Targeted disruption of either or both genes in mouse leads to spontaneous tumor formation, which is accelerated by exposure of the mutant animals to chemical carcinogens or ionizing radiation. Inactivation of ARF by mutation, deletion, or epigenetic silencing is observed in many human cancers, underscoring the role of this protein as a potent and ubiquitous tumor suppressor. p19Arf is activated by Myc or mutant Ras. Once activated, p19Arf binds to the p53 negative regulator Mdm2, leading to p53 stabilization and unleashing a p53-dependent transcriptional program that triggers either cell cycle arrest or apoptosis. p19Arf also has p53-independent inhibitory effects on cell proliferation. p19Arf is a nucleolar protein and is implicated in ribosomal biogenesis.
