Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo
Also known as: CSTF-77
Summary: The protein encoded by this gene is one of three (including CSTF1 and CSTF2) cleavage stimulation factors that combine to form the cleavage stimulation factor complex (CSTF). This complex is involved in the polyadenylation and 3' end cleavage of pre-mRNAs. The encoded protein functions as a homodimer and interacts directly with both CSTF1 and CSTF2 in the CSTF complex. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]

Data show that the recruitment of CstF subunit CstF-50 to CstF via interaction with cleavage stimulation factor, 3' pre-RNA, subunit 3, 77kDa protein (CstF-77) and establish that the hexameric assembly of CstF.
Title: Reconstitution of the CstF complex unveils a regulatory role for CstF-50 in recognition of 3'-end processing signals.
Reverse genetics and nuclear magnetic resonance studies of recombinant CstF-64 (RRM-Hinge) and CstF-77 (monkeytail-carboxy-terminal domain) indicate that the last 30 amino acids of CstF-77 increases the stability of the RRM, thus altering the affinity of the complex for RNA. These results provide new insights into the mechanism by which CstF regulates the location of the RNA cleavage site during Cleavage/polyadenylation.
Title: The structural basis of CstF-77 modulation of cleavage and polyadenylation through stimulation of CstF-64 activity.
Results from a study on gene variability markers in early-stage human embryos shows that CSTF3 is a putative variability marker for the 3-day, 8-cell embryo stage.

Thus, the conserved intronic pA of the CstF-77 gene may function as a sensor for cellular C/P and splicing activities, controlling the homeostasis of CstF-77 and C/P activity and impacting cell proliferation and differentiation.

nuclear accumulation of CstF-64 depends on binding to CstF-77 not symplekin; interaction between CstF-64/CstF-64Tau and CstF-77 are important for maintenance of nuclear levels of CstF complex components and intracellular localization, stability, function

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
