Authors have identified a putative functional indel variant at chr13q22.1 that associates with decreased DIS3 expression in carriers of pancreatic cancer risk-increasing alleles, and could therefore affect nuclear RNA processing and/or decay.
Data indicate the pathological relevance of exosome component 11 protein (DIS3) mutations in plasma cell dyscrasias and suggest that DIS3 may represent a potential tumor suppressor gene in such disorders.
structure and function of DIS3
The study establishes that the ribonuclease DIS3, targeting LIN28B (zeige LIN28B Antikörper), sustains the maturation of let-7 miRNAs and suggests the increased translation of critical oncogenes as one of the biological outcomes of DIS3 inactivation.
seven novel somatic DIS3 single nucleotide variants (SNVs) and defined three hot spot mutations within the RNB domain.
Overexpression of DIS3 and LRCH1 (zeige LRCH1 Antikörper) associated with adenoma to carcinoma progression is linked to the colorectal cancer specific gain of 13q.
Dis3p is identical to Rrp44p, which comprises the exosome involved in ribosomal RNA processing. Similar to S. cerevisiae Dis3p, human Dis3p enhanced RCC1 (zeige RCC1 Antikörper)-stimulated nucleotide release from Ran, in a dose-dependent manner, and bound to GTP (zeige AK3 Antikörper)- or GDP-Ran.
Protein-protein interactions between human exosome components support the assembly of RNase PH-type subunits into a six-membered PNPase (zeige PNPT1 Antikörper)-like ring. There appears to be no interaction between human dis3 and other exosome subunits, however.
Putative catalytic component of the RNA exosome complex which has 3'->5' exoribonuclease activity and participates in a multitude of cellular RNA processing and degradation events. In the nucleus, the RNA exosome complex is involved in proper maturation of stable RNA species such as rRNA, snRNA and snoRNA, in the elimination of RNA processing by-products and non-coding 'pervasive' transcripts, such as antisense RNA species and promoter-upstream transcripts (PROMPTs), and of mRNAs with processing defects, thereby limiting or excluding their export to the cytoplasm. The RNA exosome may be involved in Ig class switch recombination (CSR) and/or Ig variable region somatic hypermutation (SHM) by targeting AICDA deamination activity to transcribed dsDNA substrates. In the cytoplasm, the RNA exosome complex is involved in general mRNA turnover and specifically degrades inherently unstable mRNAs containing AU-rich elements (AREs) within their 3' untranslated regions, and in RNA surveillance pathways, preventing translation of aberrant mRNAs. It seems to be involved in degradation of histone mRNA. DIS3 has both 3'-5' exonuclease and endonuclease activities (By similarity).
