CC -!- FUNCTION: Polynucleotide kinase that can phosphorylate the 5'-hydroxyl
CC groups of double-stranded RNA (dsRNA), single-stranded RNA (ssRNA),
CC double-stranded DNA (dsDNA) and double-stranded DNA:RNA hybrids. dsRNA
CC is phosphorylated more efficiently than dsDNA, and the RNA component of
CC a DNA:RNA hybrid is phosphorylated more efficiently than the DNA
CC component. Plays a key role in both tRNA splicing and mRNA 3'-end
CC formation. Component of the tRNA splicing endonuclease complex:
CC phosphorylates the 5'-terminus of the tRNA 3'-exon during tRNA
CC splicing; this phosphorylation event is a prerequisite for the
CC subsequent ligation of the two exon halves and the production of a
CC mature tRNA. Its role in tRNA splicing and maturation is required for
CC cerebellar development. Component of the pre-mRNA cleavage complex II
CC (CF-II), which seems to be required for mRNA 3'-end formation. Also
CC phosphorylates the 5'-terminus of exogenously introduced short
CC interfering RNAs (siRNAs), which is a necessary prerequisite for their
CC incorporation into the RNA-induced silencing complex (RISC). However,
CC endogenous siRNAs and microRNAs (miRNAs) that are produced by the
CC cleavage of dsRNA precursors by DICER1 already contain a 5'-phosphate
CC group, so this protein may be dispensible for normal RNA-mediated gene
CC silencing (By similarity). {ECO:0000250}.
