Function

[CPSF5_HUMAN] 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.^[1] ^[2] ^[3] ^[4] ^[5] ^[6]

Publication Abstract from PubMed

Cleavage factor I(m) is an essential component of the pre-messenger RNA 3'-end processing machinery in higher eukaryotes, participating in both the polyadenylation and cleavage steps. Cleavage factor I(m) is an oligomer composed of a small 25 kDa subunit (CF I(m)25) and a variable larger subunit of either 59, 68 or 72 kDa. The small subunit also interacts with RNA, poly(A) polymerase, and the nuclear poly(A)-binding protein. These protein-protein interactions are thought to be facilitated by the Nudix domain of CF I(m)25, a hydrolase motif with a characteristic alpha/beta/alpha fold and a conserved catalytic sequence or Nudix box. We present here the crystal structures of human CF I(m)25 in its free and diadenosine tetraphosphate (Ap(4)A) bound forms at 1.85 and 1.80 A, respectively. CF I(m)25 crystallizes as a dimer and presents the classical Nudix fold. Results from crystallographic and biochemical experiments suggest that CF I(m)25 makes use of its Nudix fold to bind but not hydrolyze ATP and Ap(4)A. The complex and apo protein structures provide insight into the active oligomeric state of CF I(m) and suggest a possible role of nucleotide binding in either the polyadenylation and/or cleavage steps of pre-messenger RNA 3'-end processing.
