Superfamily: Prp8 RNase H domain, fingers region

Prp8 is the largest and most highly conserved spliceosomal protein and is considered a master regulator of the spliceosome. It forms a salt-stable complex with the Brr2 helicase that is required for spliceosome catalytic activation and disassembly and with the Snu114 GTPase that regulates Brr2 activity. Prp8 consists of a phylogenetically conserved Rnase H fold along with Prp8-specific elements. The function of this domain is to help assemble and stabilise the spliceosomal catalytic core and coordinate the activities of other splicing factors PMID:18843295.

This entry represents the all-helical fingers region of the Rnase H domain.
