Prp16p, Slu7p, and Prp8p interact with the 3' splice site in two distinct stages during the second catalytic step of pre-mRNA splicing.

RNA (New York, N.Y.) - 1 Aug 1995

Umen J G, Guthrie C

Abstract excerpt

For the second catalytic step of pre-mRNA splicing to occur, a 3' splice site must be selected and juxtaposed with the 5' exon. Four proteins, Prp16p, Slu7p, Prp17p, Prp18p, and an integral spliceosomal protein, Prp8p, are known to be required for the second catalytic step. prp8-101, an allele of PRP8 defective in 3' splice site recognition, exhibits specific genetic interactions with mutant alleles of the other...
