Pre-mRNA cleavage complex subunit Clp1, C-terminal (IPR010655)

Short name: Clp1_C

Overlapping homologous superfamilies

Domain relationships



The yeast Clp1 is a subunit of cleavage factor IA (CF IA) and is involved in mRNA cleavage and polyadenylation [PMID: 22216186]. Clp1 also mediates interactions between CF IA and another complex of the yeast mRNA cleavage and polyadenylation machinery, the Cleavage-Polyadenylation Factor (CPF) [PMID: 21993299]. It seems that human Clp1 and yeast Clp1 are not functional orthologues [PMID: 18648070]. Human Clp1, and its archeal homologue [PMID: 19299550], but not yeast Clp1, are 5'-OH polynucleotide kinases. In humans Clp1 functions as a RNA kinase important in tRNA splicing [PMID: 18648070, PMID: 24766809], and is also implicated in mRNA and siRNA maturation [PMID: 15109492, PMID: 17495927, PMID: 17786051].

This entry represents the C-terminal domain of Clp1.
