This entry represents the C-terminal domain of pre-mRNA cleavage complex II Clp1 (or HeaB) proteins. Six different protein factors are required in vitro for 3' end formation of mammalian pre-mRNAs by endonucleolytic cleavage and polyadenylation. Clp1 is a subunit of cleavage complex IIA, which is involved in the endonucleolytic cleavage during polyadenylation-dependent pre-mRNA 3'-end formation [1]. It is involved in both the endonucleolyitc cleavage and polyadenylation steps of mRNA 3'-end maturation [1]. Human Clp1 can also function as a tRNA splicing enzyme [2,3].	Domain

CLP1_P is the P-loop carrying domain of Clp1 mRNA cleavage and polyadenylation factor, Clp1, proteins in eukaryotes. Clp1 is essential for 3'-end processing of mRNAs. This region carries the P-loop suggesting it is the region that binds adenine or guanine nucleotide [1].	Domain
