✦ Synopsis

Introns within messenger RNA genes have characteristic border sequences and a conserved region near the 3' end of the intron. All are involved in splicing to produce the mature mRNA. Introns in ribosomal RNA genes have less well-defined borders and contain no internal conservation. We report here mRNA-type introns located near the 3' end of the 18s rRNA genes of the deuteromycetes Phialophora americana and Cenococcum geophilum. Inserted sequences of various sizes have also been located at the same point in several other deuteromycete species.

The Daudi cell line is characterized by an absence of HLA antigen on its surface. This has been attributed to a lack of ]~2-microglobulin (]?2m) while the heavy chain of HLA is present intracellularly.

Histone mRNAs are naturally localized on non-membrane-bound polysomes and selectively destabilized during inhibition of DNA replication. Targeting histone mRNA to membrane-bound polysomes, by incorporating sequences coding for a signal peptide into the message, results in the stabilization of the hi
