Prp8 : ウィキペディア英語版
Prp8

Prp8 refers to both the Prp8 protein and Prp8 gene. Prp8's name originates from its involvement in pre-mRNA processing. The Prp8 protein is a large, highly conserved, and unique protein that resides in the catalytic core of the spliceosome and has been found to have a central role in molecular rearrangements that occur there. Prp8 protein is a major central component of the catalytic core in the spliceosome, and the spliceosome is responsible for splicing of precursor mRNA that contains introns and exons. Unexpressed introns are removed by the spliceosome complex in order to create a more concise mRNA transcript. Splicing is just one of many different post-transcriptional modifications that mRNA must undergo before translation. Prp8 has also been hypothesized to be a cofactor in RNA catalysis.
== History ==

The systematic name for the PRP8 protein is YHR165C. Prp8 protein is coded by a single gene in humans with 42 exons. The size of Prp8 ranges between 230-280 kDa depending on the organism. The sequence coding for the Prp8 protein is highly conserved between eukaryotic organisms, with a 61% identity match between humans and yeast in amino acid sequence.〔 The Prp8 gene is located on chromosome VIII in yeast and chromosome 17 in humans.
