We have systematically measured KD (the equilibrium dissociation constant between the antibody and its antigen), of more than 840 recombinant antibodies to assess not only their individual KD values but also to see the average affinity of antibody. Based on the comparison with published literature values for mouse monoclonal antibodies, Recombinant antibodies appear to be on average 1-2 order of magnitude higher affinity.

Supplementary information

RRP42 also known as EXOSC7 is a component of the RNA exosome complex. It weighs around 28 kDa. This protein is found mainly in the nucleolus and cytoplasm where it helps with RNA processing and degradation. RRP42 acts as a scaffold within the exosome complex playing a role in structuring the exosome for interactions with other proteins and RNA substrates.
Biological function summary

RRP42 forms part of the core of the exosome complex which is essential for maintaining RNA homeostasis. This exosome complex includes several other proteins like RRP4 RRP40 and EXOSC10 creating a multiprotein assembly that processes a variety of RNA species. Through these interactions RRP42 participates in the degradation and maturation of different types of RNA like ribosomal RNA messenger RNA and small nuclear RNA.

Pathways

RRP42's role in the exosome relates to RNA metabolic processes and related pathways. It engages in the RNA processing pathway where it works on properly modifying RNA molecules. Another pathway where RRP42 is active is the surveillance pathway that protects the cell from faulty RNA. In these roles it associates with other proteins such as SKIV2L and DIS3 which also contribute to RNA turnover and quality control.

The activity of RRP42 influences conditions related to RNA processing defects. Improper function or regulation of RRP42 may associate with specific genetic disorders like pontocerebellar hypoplasia and some cancers where RNA metabolism becomes disrupted. Connections to these diseases often involve interactions with proteins like EXOSC3 and EXOSC8 which are part of the same exosome complex and contribute to the disease phenotypes through similar mechanisms.

Target data

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.
