Cleavage and polyadenylation specificity factor subunit 5

NUDT21

Status

Functioni

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 (By similarity).By similarity

Post-translational modificationi

Acetylated mainly by p300/CBP, recruited to the complex by CPSF6. Acetylation decreases interaction with PAPAO. Deacetylated by the class I/II HDACs, HDAC1, HDAC3 and HDAC10, and by the class III HDACs, SIRT1 AND SIRT2 (By similarity).By similarity

Interactioni

Subunit structurei

Homodimer. Component of the cleavage factor Im (CFIm) complex, composed of, at least, NUDT21/CPSF5 and CPSF6 or CPSF7. Within the cleavage factor Im complex, the NUDT21/CPSF5 homodimer is at the core of a heterotetramer, and is clasped by two additional subunits (CPSF6 or CPSF7). Interacts with CPSF6, CPSF7, PABPN1 and SNRNP70. Interacts with PAPOLA; the interaction is diminished by acetylation (By similarity).By similarity

100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
