RNA splicing by insect and yeast cells

[Dom Spinella]

Does anyone out there know if mammalian RNA splice signals are 
recognized by yeast and/or insect (Sf9) cells?  I have subcloned some 
constructs from a mammalian expression vector into yeast (both 
sacchromyces and pichea) and baculovirus vectors, but have left two 
short introns from the original construct intact.  These introns are 
spliced out in  mammalian cells, but it occurs to me that they may not 
be spliced correctly in lower eukaryotic cells.  I'd hate to 
re-engineer the constructs, but if I have to, I have to...
Thanks for any info.
