General annotation (Comments)

Function

Polynucleotide kinase that can phosphorylate the 5'-hydroxyl groups of double-stranded RNA (dsRNA), single-stranded RNA (ssRNA), double stranded DNA (dsDNA) and double-stranded DNA:RNA hybrids. dsRNA is phosphorylated more efficiently than dsDNA, and the RNA component of a DNA:RNA hybrid is phosphorylated more efficiently than the DNA component. Appears to have roles in both tRNA splicing and mRNA 3'-end formation. Component of the tRNA splicing endonuclease complex. Phosphorylates the 5'-terminus of the tRNA 3'-exon during tRNA splicing; this phosphorylation event is a prerequisite for the subsequent ligation of the two exon halves and the production of a mature tRNA. Component of the pre-mRNA cleavage complex II (CF-II), which seems to be required for mRNA 3'-end formation. Also phosphorylates the 5'-terminus of exogenously introduced short interfering RNAs (siRNAs), which is a necessary prerequisite for their incorporation into the RNA-induced silencing complex (RISC). However endogenous siRNAs and microRNAs (miRNAs) that are produced by the cleavage of dsRNA precursors by DICER1 already contain a 5'-phosphate group, so this protein may be dispensible for normal RNA-mediated gene silencing By similarity.

Catalytic activity

ATP + 5'-dephospho-DNA = ADP + 5'-phospho-DNA.

ATP + 5'-dephospho-RNA = ADP + 5'-phospho-RNA.

Cofactor

Magnesium, manganese or nickel By similarity.

Subunit structure

Component of the tRNA splicing endonuclease complex, composed of CLP1, TSEN2, TSEN15, TSEN34 and TSEN54. Component of pre-mRNA cleavage complex II (CF-II). Also associates with numerous components of the pre-mRNA cleavage complex I (CF-I/CFIm), including NUDT21, CPSF2, CPSF3, CPSF6 and CPSF7. Interacts with CSTF2 and SYMPK By similarity.

Subcellular location

Nucleus By similarity.

Sequence similarities

Belongs to the Clp1 family. Clp1 subfamily.
