EXOSC5 is a member of the RNase PH family. EXOSC5 is known to cooperate with Exosome component 8 and Exosome component 1. EXOSC5 is a Non-catalytic component of the RNA exosome complex and has 3'->5' exoribonuclease activity. EXOSC5 take part in a large number of cellular RNA processing and degradation events. EXOSC5 is expressed in a large range of hematopoietic and epithelial tumor cell lines, but not in standard hematopoietic tissues or other standard tissue, with the exception of testis.

EXOSC5 Human Recombinant produced in�E. coli is a single polypeptide chain containing 256 amino acids (1-235) and having a molecular mass of 27.5kDa.EXOSC5 is fused to a 21 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.

UniProt Protein Function:EXOSC5: Non-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. The catalytic inactive RNA exosome core complex of 9 subunits (Exo-9) is proposed to play a pivotal role in the binding and presentation of RNA for ribonucleolysis, and to serve as a scaffold for the association with catalytic subunits and accessory proteins or complexes. Belongs to the RNase PH family.
