Modification of program enables prediction of gene transcription

... the May 2005 issue of Genome Research. N-SCAN has proven to be the best program available at finding both the transcription start site (TSS) and the complete first exon in both the human and fruit fly genomes. The addition of N-SCAN to TWINSCAN now provides genomics researchers the wherewithal to find and...

Hopkins scientists uncover 'tags' that force proteins to cell surface

...cell surface isn't, and in the lab, sometimes it's proven impossible to get a protein to the cell surface in order to study it. The tags we've found might help us force proteins to the surface, which offers real hope for overcoming these hurdles." Laboratory studies in which the tags might be used to force...
