Cleavage stimulation factor subunit 3; One of the multiple factors required for polyadenylation and 3’-end cleavage of mammalian pre-mRNAs (717 aa)

Cleavage and polyadenylation specificity factor subunit 2; Component of the cleavage and polyadenylation specificity factor (CPSF) complex that play a key role in pre-mRNA 3’-end formation, recognizing the AAUAAA signal sequence and interacting with poly(A) polymerase and other factors to bring about cleavage and poly(A) addition. Involved in the histone 3’ end pre-mRNA processing; Belongs to the metallo-beta-lactamase superfamily. RNA-metabolizing metallo-beta-lactamase-like family. CPSF2/YSH1 subfamily (782 aa)

RNA-binding motif protein, X chromosome; RNA-binding protein that plays several role in the regulation of pre- and post-transcriptional processes. Implicated in tissue-specific regulation of gene transcription and alternative splicing of several pre-mRNAs. Binds to and stimulates transcription from the tumor suppressor TXNIP gene promoter; may thus be involved in tumor suppression. When associated with SAFB, binds to and stimulates transcription from the SREBF1 promoter. Associates with nascent mRNAs transcribed by RNA polymerase II. Component of the supraspliceosome complex that regul [...] (391 aa)

Cleavage and polyadenylation specificity factor subunit 1; Component of the cleavage and polyadenylation specificity factor (CPSF) complex that plays a key role in pre- mRNA 3’-end formation, recognizing the AAUAAA signal sequence and interacting with poly(A) polymerase and other factors to bring about cleavage and poly(A) addition. This subunit is involved in the RNA recognition step of the polyadenylation reaction (1443 aa)

N6-adenosine-methyltransferase catalytic subunit; The METTL3-METTL14 heterodimer forms a N6- methyltransferase complex that methylates adenosine residues at the N(6) position of some RNAs and regulates various processes such as the circadian clock, differentiation of embryonic and haematopoietic stem cells, cortical neurogenesis, response to DNA damage, differentiation of T-cells and primary miRNA processing. In the heterodimer formed with METTL14, METTL3 constitutes the catalytic core. N6-methyladenosine (m6A), which takes place at the 5’-[AG]GAC-3’ consensus sites of some mRNAs, play [...] (580 aa)

N6-adenosine-methyltransferase non-catalytic subunit; The METTL3-METTL14 heterodimer forms a N6- methyltransferase complex that methylates adenosine residues at the N(6) position of some mRNAs and regulates the circadian clock, differentiation of embryonic stem cells and cortical neurogenesis. In the heterodimer formed with METTL3, METTL14 constitutes the RNA-binding scaffold that recognizes the substrate rather than the catalytic core. N6- methyladenosine (m6A), which takes place at the 5’-[AG]GAC-3’ consensus sites of some mRNAs, plays a role in mRNA stability and processing. M6A act [...] (456 aa)

Cleavage and polyadenylation specificity factor subunit 5; Component of the cleavage factor Im (CFIm) complex that plays a key role in pre-mRNA 3’-processing. Involved in association with CPSF6 or CPSF7 in pre-MRNA 3’-end poly(A) site cleavage and poly(A) addition. NUDT21/CPSF5 binds to cleavage and polyadenylation RNA substrates. The homodimer mediates simultaneous sequence-specific recognition of two 5’-UGUA-3’ elements within the pre-mRNA. Binds to, but does not hydrolyze mono- and di-adenosine nucleotides. May have a role in mRNA export; Nudix hydrolase family (227 aa)

Cleavage stimulation factor subunit 1; One of the multiple factors required for polyadenylation and 3’-end cleavage of mammalian pre-mRNAs. May be responsible for the interaction of CSTF with other factors to form a stable complex on the pre-mRNA (431 aa)
