The τCstF-64 Polyadenylation Protein Controls Genome Expression in Testis
The τCstF-64 polyadenylation protein (gene symbol Cstf2t) is a testis-expressed orthologue of CstF-64. Mice in which Cstf2t was knocked out had a phenotype that was only detected in meiotic and postmeiotic male germ cells, giving us the opportunity to examine CstF-64 function in an isolated developmental system. We performed massively parallel clonally amplified sequencing of cDNAs from testes ...
متن کاملEnterovirus 71 3C Protease Cleaves a Novel Target CstF-64 and Inhibits Cellular Polyadenylation
Identification of novel cellular proteins as substrates to viral proteases would provide a new insight into the mechanism of cell-virus interplay. Eight nuclear proteins as potential targets for enterovirus 71 (EV71) 3C protease (3C(pro)) cleavages were identified by 2D electrophoresis and MALDI-TOF analysis. Of these proteins, CstF-64, which is a critical factor for 3' pre-mRNA processing in a...
متن کاملCstF-64 supports pluripotency and regulates cell cycle progression in embryonic stem cells through histone 3′ end processing
Embryonic stem cells (ESCs) exhibit a unique cell cycle with a shortened G1 phase that supports their pluripotency, while apparently buffering them against pro-differentiation stimuli. In ESCs, expression of replication-dependent histones is a main component of this abbreviated G1 phase, although the details of this mechanism are not well understood. Similarly, the role of 3' end processing in ...
متن کاملInteractions of CstF-64, CstF-77, and symplekin: Implications on localisation and function
Cleavage/polyadenylation of mRNAs and 3' processing of replication-dependent histone transcripts are both mediated by large complexes that share several protein components. Functional studies of these shared proteins are complicated by the cooperative binding of the individual subunits. For CstF-64, an additional difficulty is that symplekin and CstF-77 bind mutually exclusively to its hinge do...
متن کاملThe Cstf2t Polyadenylation Gene Plays a Sex-Specific Role in Learning Behaviors in Mice
Polyadenylation is an essential mechanism for the processing of mRNA 3' ends. CstF-64 (the 64,000 Mr subunit of the cleavage stimulation factor; gene symbol Cstf2) is an RNA-binding protein that regulates mRNA polyadenylation site usage. We discovered a paralogous form of CstF-64 called τCstF-64 (Cstf2t). The Cstf2t gene is conserved in all eutherian mammals including mice and humans, but the τ...
