CPSF_A

• PFAM accession number: PF03178
• Interpro abstract (IPR004871):

  This family includes a region that lies towards the C terminus of the cleavage and polyadenylation specificity factor (CPSF) A (160kDa) subunit. CPSF is involved in mRNA polyadenylation and binds the AAUAAA conserved sequence in pre-mRNA. CPSF has also been found to be necessary for splicing of single-intron pre-mRNAs [ (PUBMED:11421366) ]. The function of the aligned region is unknown but may be involved in RNA/DNA binding.

• GO component: nucleus (GO:0005634)
• GO function: nucleic acid binding (GO:0003676)

This is a PFAM domain. For full annotation and more information, please see the PFAM entry CPSF_A
