Ink4a/arf位点
Webb1 maj 2000 · The INK4a/ARF locus is regarded as one of the most important anti-tumoral defenses that mammalian organisms possess. The characterization of its two gene products, p16 INK4a and p19 ARF, has provided a great insight on the functioning of … p14ARF (also called ARF tumor suppressor, ARF, p14 ) is an alternate reading frame protein product of the CDKN2A locus (i.e. INK4a/ARF locus). p14ARF is induced in response to elevated mitogenic stimulation, such as aberrant growth signaling from MYC and Ras (protein). It accumulates mainly in the nucleolus where it forms stable complexes with NPM or Mdm2. These interactions allow p14ARF to act as a tumor suppressor by inhibiting ribosome biogenesis or initiat…

WebbINK4a/ARF/INK4b遺伝子座は、3つのタンパク質（p15 INK4b 、ARF、p16 INK4a ）をコードする、ヒトゲノム上の35 kbの領域である。 p15 INK4b は、p16 INK4a 、ARFとは物理的に離れた異なるリーディングフレームを持つ。 一方、p16 INK4a とARFは最初 … INK4 is a family of cyclin-dependent kinase inhibitors (CKIs). The members of this family (p16 , p15 , p18 , p19 ) are inhibitors of CDK4 (hence their name INhibitors of CDK4), and of CDK6. The other family of CKIs, CIP/KIP proteins are capable of inhibiting all CDKs. Enforced expression of INK4 proteins can lead … Visa mer The INK4a/ARF/INK4b locus encodes three genes (p15INK4b, ARF, and p16INK4a) in a 35-kilobase stretch of the human genome. P15INK4b has a different reading frame that is physically separated from p16INK4a and … Visa mer Polymorphisms of the p15INK4b/p16INK4a homolog were found to segregate with melanoma susceptibility in the Xiphophorus indicating that INK4 proteins have been … Visa mer P16INK4a P16 is formed from four ankyrin repeat (AR) motifs that exhibit a helix-turn-helix conformation except that the first helix in the second AR consists of four residues. P16 regulation involves epigenetic control and multiple … Visa mer Initially, it was thought that each INK4 family member was structurally redundant and equally potent. It was later found; however, that INK4 family members are differentially … Visa mer INK4 proteins are cell-cycle inhibitors. When they bind to CDK4 and CDK6, they induce an allosteric change that leads to the formation of CDK-INK4 complexes rather than CDK-cyclin complexes. This leads to an inhibition of retinoblastoma (Rb) … Visa mer Role in cancer Cells containing oncogenic mutations in-vivo often responded by activating the INK4A/ARF/INK4B locus that encodes the INK4 tumor … Visa mer
