p14ARF是近年来发现的一种重要的抑癌基因,与细胞周期和凋亡的调控密切相关,p14ARF基因是细胞周期调控基因,它主要阻滞细胞于G1期和G2/M期,因此p14ARF与癌细胞的增殖和凋亡密切相关,在肿瘤的发生和演化中起着重要的作用。
p14ARF主要定位于细胞核,但也有部分定位于胞浆,与细胞周期有关。
This gene generates several transcript variants which differ in their first exons. At least three alternatively spliced variants encoding distinct proteins have been reported, two of which encode structurally related isoforms known to function as inhibitors of CDK4 kinase. The remaining transcript includes an alternate first exon located 20 Kb upstream of the remainder of the gene; this transcript contains an alternate open reading frame (ARF) that specifies a protein which is structurally unrelated to the products of the other variants. This ARF product functions as a stabilizer of the tumor suppressor protein p53 as it can interact with, and sequester, MDM1, a protein responsible for the degradation of p53. In spite of the structural and functional differences, the CDK inhibitor isoforms and the ARF product encoded by this gene, through the regulatory roles of CDK4 and p53 in cell cycle G1 progression, share a common functionality in cell cycle G1 control. This gene is frequently mutated or deleted in a wide variety of tumors, and is known to be an important tumor suppressor gene. CDKN2A.
