B, D [auth E] | PF10597 | U5-snRNA binding site 2 of PrP8 (U5_2-snRNA_bdg) | U5-snRNA binding site 2 of PrP8 | The essential spliceosomal protein Prp8 interacts with U5 and U6 snRNAs and with specific pre-mRNA sequences that participate in catalysis [1]. This close association with crucial RNA sequences, together with extensive genetic evidence, suggests that ... | Domain |
B, D [auth E] | PF10598 | RNA recognition motif of the spliceosomal PrP8 (RRM_4) | RNA recognition motif of the spliceosomal PrP8 | The large RNA-protein complex of the spliceosome catalyses pre-mRNA splicing. One of the most conserved core proteins is PrP8 which occupies a central position in the catalytic core of the spliceosome, and has been implicated in several crucial molec ... | Domain |
B, D [auth E] | PF10596 | U6-snRNA interacting domain of PrP8 (U6-snRNA_bdg) | U6-snRNA interacting domain of PrP8 | This domain incorporates the interacting site for the U6-snRNA as part of the U4/U6.U5 tri-snRNPs complex of the spliceosome, and is the prime candidate for the role of cofactor for the spliceosome's RNA core. The essential spliceosomal protein Prp8 ... | Domain |
