SPT10 is one member of a large class of SPT genes, which were named for their ability to suppress the phenotypes resulting from Ty insertions that disrupted transcription of nearby genes (8). Genes with this phenotype include the TATA binding protein, some histones, regulators of histone gene expression, and members of the SAGA histone acetyltransferase complex (8). Spt10p is thought to be involved in chromatin maintenance and transcriptional regulation, and mutations in Spt10p are suppressed by the transcriptional regulator Ccr4p (9, 10). Spt10p is required for transcription of some but not all of the histone genes (11). It is not an essential gene, but deletion of SPT10 causes very slow growth and results in increased expression from several otherwise repressed promoters (3, 1, 12). One domain of Spt10p has similarity to a Zn-finger motif, and this domain is associated with Spt10p's transcriptional regulation (but is not involved in the slow growth phenotype of the mutant) (1).
