In addition to Jim's impressive report, with Entrez (on WWW, Network or CD-ROM)
you can get the Nucleotide, Protein and bibliographic 'neighbors' ... I
attach a couple of the Medline article which are in Entrez.

If you want to know more about Entrex, send some info requests to

The Saccharomyces cerevisiae SPT7 gene encodes a very acidic protein important
for transcription in vivo.

Mutations in the SPT7 gene of Saccharomyces cerevisiae originally were
identified as suppressors of Ty and delta insertion mutations in the 5' regions
of the HIS4 and LYS2 genes. Other genes that have been identified in mutant
hunts of this type have been shown to play a role in transcription. In this
work we show that SPT7 is also important for proper transcription in vivo. We
have cloned and sequenced the SPT7 gene and have shown that it encodes a large,
acidic protein that is localized to the nucleus. The SPT7 protein contains a
bromodomain sequence; a deletion that removes the bromodomain from the SPT7
protein causes no detectable mutant phenotype. Strains that contain an spt7
null mutation are viable but grow very slowly and have transcriptional defects
at many loci including insertion mutations, Ty elements, the INO1 gene and the
MFA1 gene. These transcriptional defects and other mutant phenotypes are
similar to those caused by certain mutations in SPT15, which encodes the TATA
binding protein (TBP). The similarity of the phenotypes of spt7 and spt15
mutants, including effects of spt7 mutations on the transcription start site of
certain genes, suggests that SPT7 plays an important role in transcription
initiation in vivo.
