TEXT

Gene Function

Splicing of nuclear precursor-mRNA (pre-mRNA) is the process by which introns are removed from mRNA precursors to form functional mature mRNAs. The process is mediated by the spliceosome, a complex ribonucleoprotein composed of 5 small nuclear RNAs (U1, 180680; U2, 180690; U3, 180710; U5; and U6, 180692) and numerous proteins. Introns are removed by means of 2 consecutive transesterification reactions. Introns are defined only by 3 short consensus sequences: the 5-prime splice site, the branch point region, and 3-prime splice site. Sontheimer and Steitz (1993) characterized the U5 and U6 snRNAs as components of the active site of the spliceosome. Wise (1993) reviewed the functioning of the spliceosome.


Mapping

Gross (2023) mapped the RNU5A-1 gene to chromosome 15q22.31 based on an alignment of the RNU5A-1 sequence (GenBank NR_002756) with the genomic sequence (GRCh38).
