SWI1

ADR6, GAM3, LPA1, [SWI(+)], [SWI+], L000000052, L000002250, YPL016W
Subunit of the SWI/SNF chromatin remodeling complex; regulates transcription by remodeling chromatin; required for transcription of many genes, including ADH1, ADH2, GAL1, HO, INO1 and SUC2; can form the prion [SWI+]; human homolog ARID1A is a candidate tumor suppressor gene in breast cancer
Saccharomyces cerevisiae (S288c)

Two-hybrid

Bait protein expressed as a DNA binding domain (DBD) fusion and prey expressed as a transcriptional activation domain (TAD) fusion and interaction measured by reporter gene activation.

Functional contacts with a range of splicing proteins suggest a central role for Brr2p in the dynamic control of the order of events in spliceosomes of Saccharomyces cerevisiae.

van Nues RW, Beggs JD

Mapping of functional protein interactions will help in understanding conformational rearrangements that occur within large complexes like spliceosomes. Because the U5 snRNP plays a central role in pre-mRNA splicing, we undertook exhaustive two-hybrid screening with Brr2p, Prp8p, and other U5 snRNP-associated proteins. DExH-box protein Brr2p interacted specifically with five splicing factors: Prp8p, DEAH-box protein Prp16p, U1 snRNP protein Snp1p, second-step ... [more]
