A novel mechanism of aberrant pre-mRNA splicing in humans.
Eukaryotic pre-mRNA splicing is regulated by consensus sequences at the intron boundaries and branch site. Recently, Sirand-Pugnet et al. reported the importance of an additional intronic sequence, an (A/U)GGG repeat in chicken beta-tropomyosin that is a binding site for a protein required for spliceosome assembly. Interestingly, we have detected mutations in IVS3 of the human growth hormone (G...
متن کاملRegulated tissue-specific expression of antagonistic pre-mRNA splicing factors.
The SR proteins are essential metazoan pre-mRNA splicing factors that can also influence the selection of alternative 5' splice sites in a concentration-dependent manner. Their activity in alternative splicing in vitro is antagonized by members of the hnRNP A/B family of proteins. The opposite effects of members of these two families of antagonistic splicing factors in vitro and upon overexpres...
متن کاملMechanism for cryptic splice site activation during pre-mRNA splicing.
The 5' splice site of a pre-mRNA is recognized by U1 small nuclear ribonucleoprotein particles (snRNP) through base pairing with the 5' end of U1 small nuclear RNA (snRNA). Single-base substitutions within a 9-nucleotide 5'-splice-site sequence can abolish or attenuate use of that site and, in higher eukaryotes, can also activate nearby "cryptic" 5' splice sites. Here we show that the effects o...
متن کاملRNAcatalyses nuclear pre-mRNA splicing
In nuclear pre-messenger RNA splicing, introns are excised by the spliceosome, a dynamic machine composed of both proteins and small nuclear RNAs (snRNAs). Over thirty years ago, after the discovery of self-splicing group II intron RNAs, the snRNAswere proposed to catalyse splicing. However, no definitive evidence for a role of either RNAor protein in catalysis by the spliceosome has been repor...
