Cleavage and polyadenylation specific factor 3, 73kDa

Most eukaryotic mRNA precursors (pre-mRNAs) undergo extensive maturational processing, including cleavage and polyadenylation at the 3-prime end. CPSF3 encodes the 73-kD subunit of the cleavage and polyadenylation specificity factor (CPSF) and is the pre-mRNA 3-prime-end-processing endonuclease (Mandel et al., 2006 [PubMed 17128255]).[supplied by OMIM, Jul 2010] (from NCBI)

Based on tandem-affinity purification with tagged CPSF160 and mass spectrometry, we identified ten associated components of the trypanosome polyadenylation complex, including homologues to all four CPSF subunits, Fip1, CstF50/6;4, and Symplekin, as well as two hypothetical proteins.

Three β-CASP orthologous groups, aCPSF1, aCPSF2, aCPSF1b, are closely related to the eukaryal CPSF73 termination factor and one, aRNase J, is ortholog of the bacterial RNase J.

Hüttelmaier et al., Halle, Germany. In Genes Dev, Nov 2015
We demonstrate that the Y3/Y3** noncoding RNAs (ncRNAs) bind to the CPSF (cleavage and polyadenylation specificity factor) and that Y3** associates with the 3' untranslated region (UTR) of histone pre-mRNAs.
A Biogenesis Step Upstream of Microprocessor Controls miR-17∼92 Expression.
Gregory et al., Boston, United States. In Cell, Sep 2015
The endonuclease CPSF3 (CPSF73) and the spliceosome-associated ISY1 are responsible for pro-miRNA biogenesis and expression of all miRNAs within the cluster except miR-92.
In vivo characterization of the Drosophila mRNA 3' end processing core cleavage complex.
Steiniger et al., Saint Louis, United States. In Rna, Aug 2015
A core cleavage complex (CCC) consisting of CPSF73, CPSF100, and Symplekin is required for cotranscriptional 3' end processing of all metazoan pre-mRNAs, yet little is known about the in vivo molecular interactions within this complex.
Global Promotion of Alternative Internal Exon Usage by mRNA 3' End Formation Factors.
Green et al., Worcester, United States. In Mol Cell, Jul 2015
Unexpectedly, we find that two mRNA 3' end formation factors, cleavage and polyadenylation specificity factor (CPSF) and SYMPK, are RBFOX2 cofactors for both inclusion and exclusion of internal exons.
CPSF30 at the Interface of Alternative Polyadenylation and Cellular Signaling in Plants.
Hunt et al., Lexington, United States. In Biomolecules, 2014
A considerable amount of research has been done in characterizing different subunits of so-called Cleavage and Polyadenylation Specificity Factor (CPSF).

Recent phylogenomic analyses have shown that the β-CASP ribonucleases can be partitioned into two major subdivisions that correspond to orthologs of eukaryal CPSF73 and bacterial RNase J.
Few Smad proteins and many Smad-interacting proteins yield multiple functions and action modes in TGFβ/BMP signaling in vivo.

In this survey, we selected appropriate examples on the BMP-Smads, with emphasis on Smad1 and Smad5, and on a number of SIPs, i.e. the CPSF subunit Smicl, Ttrap (Tdp2) and Sip1 (Zeb2, Zfhx1b) from our own research carried out in three different vertebrate models.

The poly A polymerase Star-PAP controls 3'-end cleavage by promoting CPSF interaction and specificity toward the pre-mRNA.
Anderson et al., Madison, United States. In Embo J, 2011
The data support a model where Star-PAP binds to the pre-mRNA, recruits the CPSF complex to the 3'-end of pre-mRNA and then defines cleavage by CPSF 73 and subsequent polyadenylation of its target mRNAs.

Degradation of the downstream cleavage product (DCP) does not depend on the Xrn2 5' exonuclease, suggesting that CPSF-73 degrades the DCP both in vitro and in vivo.

Richter et al., Worcester, United States. In Cell, 2004
In Xenopus oocytes, where the molecular mechanism has been defined, the core factors that control this process include CPEB, an RNA binding protein whose association with the CPE specifies which mRNAs undergo polyadenylation; CPSF, a multifactor complex that interacts with the near-ubiquitous polyadenylation hexanucleotide AAUAAA; and maskin, a CPEB and eIF4E binding protein whose regulation of initiation is governed by poly(A) tail length.
