Inhibitor AN3661 reveals biological functions of Arabidopsis CLEAVAGE AND POLYADENYLATION SPECIFICITY FACTOR 73.

Plant Physiology, 2023
Cleavage and polyadenylation specificity factor (CPSF) is a protein complex that plays an essential biochemical role in mRNA 3'-end formation, including poly(A) signal recognition and cleavage at the poly(A) site. However, its biological functions at the

Crystal structure of a dimeric archaeal Cleavage and Polyadenylation Specificity Factor

open access: closedJournal of Structural Biology, 2010
Proteins of the metallo-β-lactamase (MβL) fold form a large superfamily of metallo-hydrolase/oxidoreductases. Members of this family are found in all three domains of life and are involved in a variety of biological functions related to hydrolysis, redox processes, DNA repair and uptake, and RNA processing.

Essential Yeast Protein with Unexpected Similarity to Subunits of Mammalian Cleavage and Polyadenylation Specificity Factor (CPSF)

open access: closedScience, 1996
The 3′ ends of most eukaryotic messenger RNAs are generated by internal cleavage and polyadenylation. In mammals, there is a strict dependence of both reactions on the sequence AAUAAA, which occurs upstream of polyadenylation [poly(A)] sites and which is recognized by CPSF.

The 73 kD Subunit of the cleavage and polyadenylation specificity factor (CPSF) complex affects reproductive development in Arabidopsis

open access: closedPlant Molecular Biology, 2006
The cleavage and polyadenylation specificity factor (CPSF) is an important multi-subunit component of the mRNA 3'-end processing apparatus in eukaryotes. The Arabidopsis genome contains five genes encoding CPSF homologues (AtCPSF160, AtCPSF100, AtCPSF73-I, AtCPSF73-II and AtCPSF30).

Cleavage and Polyadenylation Specificity Factor 1 Is Required for Definitive Hematopoietic Stem Cell Survival In Zebrafish.

open access: closedBlood, 2010
Abstract Abstract 1606 Hematopoiesis is a tightly regulated process requiring the differential activation of specific genetic programs. Inactivating mutations of genes involved in normal hematopoiesis have been implicated in bone marrow failure syndromes, myelodysplastic syndromes and hematopoietic neoplasms.

Cleavage and polyadenylation specific factor 4 promotes colon cancer progression by transcriptionally activating hTERT

open access: closedBiochimica et Biophysica Acta (BBA) - Molecular Cell Research, 2019
CPSF4 was identified as a crucial tumorigenic factor in lung cancer development. However, its precise function and the underlying molecular mechanisms in colon cancer progression remain completely unknown. Here, we demonstrate CPSF4 was highly expressed in human colon cancer cells and tissues.

Separation and characterization of a poly(A) polymerase and a cleavage/specificity factor required for pre-mRNA polyadenylation

open access: closedCell, 1988
To study the mechanism and factors required to form the 3' ends of polyadenylated mRNAs, we have fractionated HeLa cell nuclear extracts carrying out the normally coupled cleavage and polyadenylation reactions. Each reaction is catalyzed by a distinct, separable activity.
