In vitro splicing of fibronectin pre-mRNAs.


We have investigated the alternative splicing of the EIIIB exon of the rat fibronectin gene. Mini-gene constructs containing this exon and portions of adjacent introns and exons, when transfected into HeLa cells, are transcribed and spliced, but omit the EIIIB exon. In vitro, HeLa nuclear extracts similarly splice out (skip) the EIIIB exon from similarly… (More)
