General annotation (Comments)

Function

Component of the cleavage factor Im (CFIm) complex that plays a key role in pre-mRNA 3'-processing. Involved in association with CPSF6 in pre-MRNA 3'-end poly(A) site cleavage and poly(A) addition. NUDT21/CPSF5 binds to cleavage and polyadenylation RNA substrates. Ref.1 Ref.5 Ref.6

Subunit structure

Component of the cleavage factor Im (CFIm) complex, composed at least of NUDT21/CPSF5 and CPSF6 or CPSF7. Interacts with CPSF6, PAPOLA, PABPN1 and SNRP70. Ref.7 Ref.8

Subcellular location

Nucleus. Note= In punctate subnuclear structures localized adjacent to nuclear speckles, called paraspeckles. Ref.1 Ref.8

Sequence similarities

Belongs to the Nudix hydrolase family. CPSF5 subfamily.

Contains 1 nudix hydrolase domain.
