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

This supplementary information is collated from multiple sources and compiled automatically.

CPSF73 also known as Cleavage and Polyadenylation Specificity Factor 73 is an important component of the mRNA processing machinery. Mechanically CPSF73 functions as an endonuclease that cleaves pre-mRNA at the 3' end a necessary step for the addition of a poly(A) tail. CPSF73 has a molecular mass of approximately 73 kDa. This protein is expressed ubiquitously across various cell types reflecting its essential role in gene expression regulation.
Biological function summary

The mRNA processing involves CPSF73 as part of the larger cleavage and polyadenylation complex. This complex is responsible for recognizing specific cleavage sites within pre-mRNA and is critical for mRNA maturation. CPSF73’s activity ensures the proper maturation of messenger RNA facilitating its export from the nucleus translation into proteins and subsequent degradation. The endonuclease works closely with other components of the complex including CPSF160 CPSF100 and CFIm suggesting that its role extends beyond just cleavage to broader mRNA stability and regulation.

Pathways

CPSF73 actively participates in the mRNA processing pathway playing an integral role in post-transcriptional regulation. It also interfaces with the spliceosome machinery illustrating the crosstalk between pre-mRNA splicing and polyadenylation sites. CPSF73 is closely related to other RNA processing proteins such as CstF-64 and Symplekin which together maintain the precise regulation of gene expression. This interrelation is particularly important in pathways where timing of mRNA processing impacts cellular function and response.

CPSF73's malfunction could lead to serious implications including cancer and genetic disorders. Aberrant expression or mutations in CPSF73 have been linked to various cancers as they directly affect mRNA maturation and stability which could result in unchecked cell proliferation. Furthermore its connection with proteins such as CPSF160 has been observed in cancers where dysregulation of mRNA processing pathways contribute to tumorigenesis. Disorders like these highlight the necessity of CPSF73 for maintaining cellular health and proper gene expression.

Target data

Component of the cleavage and polyadenylation specificity factor (CPSF) complex that plays a key role in pre-mRNA 3'-end formation, recognizing the AAUAAA signal sequence and interacting with poly(A) polymerase and other factors to bring about cleavage and poly(A) addition. Has endonuclease activity, and functions as an mRNA 3'-end-processing endonuclease (PubMed : 30507380). Also involved in the histone 3'-end pre-mRNA processing (PubMed : 30507380). U7 snRNP-dependent protein that induces both the 3'-endoribonucleolytic cleavage of histone pre-mRNAs and acts as a 5' to 3' exonuclease for degrading the subsequent downstream cleavage product (DCP) of mature histone mRNAs. Cleavage occurs after the 5'-ACCCA-3' sequence in the histone pre-mRNA leaving a 3'hydroxyl group on the upstream fragment containing the stem loop (SL) and 5' phosphate on the downstream cleavage product (DCP) starting with CU nucleotides. The U7-dependent 5' to 3' exonuclease activity is processive and degrades the DCP RNA substrate even after complete removal of the U7-binding site. Binds to the downstream cleavage product (DCP) of histone pre-mRNAs and the cleaved DCP RNA substrate in a U7 snRNP dependent manner. Required for entering/progressing through S-phase of the cell cycle (PubMed : 30507380). Required for the selective processing of microRNAs (miRNAs) during embryonic stem cell differentiation via its interaction with ISY1 (By similarity). Required for the biogenesis of all miRNAs from the pri-miR-17-92 primary transcript except miR-92a (By similarity). Only required for the biogenesis of miR-290 and miR-96 from the pri-miR-290-295 and pri-miR-96-183 primary transcripts, respectively (By similarity).
