WebJul 7, 1998 · The INK4a-ARF locus encodes two proteins, p16 INK4a and p19 ARF, that restrain cell growth by affecting the functions of the retinoblastoma protein and p53, respectively.Disruption of this locus by deletions or point mutations is a common event in human cancer, perhaps second only to the loss of p53. Using insect cells infected with … WebJun 6, 2013 · Several tumor suppressors and oncoproteins regulate the MDM2-p53 interaction. Ribosomal proteins (RP-both the large subunit and small subunits) form a complex with p53 and MDM2 to inhibit MDM2-mediated p53 ubiquitination and stabilization of p53. ARF and PML sequester the MDM2 in the nucleolus, inhibiting MDM2 from …
WebThe function of ARF has primarily been attributed to its Mdm2/p53 mechanism. ARF does, however, also inhibit proliferation in cells lacking p53 or p53 and Mdm2. In 2004 has … WebThe INK4a–ARF locus is a common target of deletion and mutation in human cancers, possibly second in frequency only to p53. The product of the INK4a gene, p16 INK4a, acts as an inhibitor of cyclin D-dependent kinases, preventing them from phosphorylating the retinoblastoma (pRb) protein and thus inhibiting S-phase entry during the cell division …
