| '''Pre-mRNA-splicing factors (Prp)''' are the proteins which associate with mRNA at its various splicing sites to produce alternative splicing. For details on pre-mRNA-splicing factors see [[Prp24]]; [[Prp19]]; [[Prp40]]. | | *'''Prp3b''' is part of the U2 small nuclear ribonucleoproteins complex (U2 snRNP)<br /> |
| | *'''Prp8''' functions as a scaffold which mediates the ordered assembly of spliceosomal proteins and snRNAs. For details see [[Prp8]]<br /> |
| | *'''Prp18''' and '''Bud31''' are essential for the catalytic step in pre-mRNA splicing process.<br /> |
| | *'''snRNA-associated-splicing factor 24''' binds preferentially to the U4/U6 hybrid snRNAs. For details see [[Prp24]]<br /> |
