The APT complex is involved in non-coding RNA transcription and is distinct from CPF [ChIP-seq]

Project description:The 3′-ends of eukaryotic pre-mRNAs are processed in the nucleus by a large multiprotein complex, the cleavage and polyadenylation factor (CPF). CPF cleaves RNA, adds a poly(A) tail and signals transcription termination. CPF harbors four enzymatic activities essential for these processes but how these are coordinated remains poorly understood. Several subunits of the CPF including two protein phosphatases are also found in a related complex, the ‘associated with Pta1’ (APT) complex, but the relationship between CPF and APT is unclear. Here, we show that the APT complex is physically distinct from CPF. The 21 kDa Syc1 protein is associated only with APT, and not with CPF, and is therefore the defining subunit of APT. Using ChIP-seq, PAR-CLIP and RNA-seq, we show that Syc1 has functions separable from those of CPF. Syc1 plays a role in sn/snoRNA production whereas CPF processes the 3ʹ-ends of protein-coding pre-mRNAs. These results define distinct protein machineries for synthesis of mature eukaryotic protein-coding and non-coding RNAs.

Syc1/APT plays a more important role in sn/snoRNA production whereas CPF processes the 3'-ends of protein-coding pre-mRNAs. These results define distinct protein machineries for synthesis of mature eukaryotic protein-coding and non-coding RNAs.

Identiﬁcation of Drosophila TDF/Apt regulated genes in embryos

Project description:Drosophila tdf, another name apontic (apt), encodes a bZIP transcription factor that is required for the development of trachea, heart, head and neural system. However, little is known about the target of TDF/Apt. To identify theTDF/ Apt regulated genes, we compared expression profiles of mRNA purified from wild-type and tdf mutant embryos. Summary file is emtdf-yw.CHP.
