SPN1

IWS1, YPR133C
Protein involved in RNA polymerase II transcription; is constitutively recruited to the CYC1 promoter and is required for recruitment of chromatin remodeling factors for the expression of CYC1 gene; interacts genetically or physically with RNAP II, TBP, TFIIS, and chromatin remodelling factors; central domain highly conserved throughout eukaryotes; mutations confer an Spt- phenotype
Saccharomyces cerevisiae (S288c)

HHT1

BUR5, SIN2, histone H3, L000000772, YBR010W
Histone H3; core histone protein required for chromatin assembly, part of heterochromatin-mediated telomeric and HM silencing; one of two identical histone H3 proteins (see HHT2); regulated by acetylation, methylation, and phosphorylation; H3K14 acetylation plays an important role in the unfolding of strongly positioned nucleosomes during repair of UV damage
Saccharomyces cerevisiae (S288c)

Reconstituted Complex

An interaction is detected between purified proteins in vitro.

The process of transcriptional elongation by RNA polymerase II (RNAPII) in a chromatin context involves a large number of crucial factors. Spn1 is a highly conserved protein encoded by an essential gene and is known to interact with RNAPII and the histone chaperone Spt6. Spn1 negatively regulates the ability of Spt6 to interact with nucleosomes, but the chromatin binding properties ... [more]
