HSL7
L000003130, YBR133C
Protein arginine N-methyltransferase; exhibits septin and Hsl1p-dependent bud neck localization and periodic Hsl1p-dependent phosphorylation; required along with Hsl1p for bud neck recruitment, phosphorylation, and degradation of Swe1p; relocalizes away from bud neck upon DNA replication stress

SET1
YTX1, histone methyltransferase SET1, KMT2, L000003286, YHR119W
Histone methyltransferase, subunit of the COMPASS (Set1C) complex; COMPASS methylates histone H3K4; Set1p-dependent H3K4 trimethylation recruits Nrd1p, allowing efficient termination of snoRNAs and cryptic unstable transcripts (CUTs) by Nrd1p-Nab3p-Sen1p pathway; modulates histone acetylation levels in promoter proximal regions to ensure efficient Nrd1p-dependent termination; required in transcriptional silencing near telomeres and at silent mating type loci; has a SET domain

Synthetic Lethality
A genetic interaction is inferred when mutations or deletions in separate genes, each of which alone causes a minimal phenotype, result in lethality when combined in the same cell under a given condition.
Publication
Chromatin-modifiying enzymes are essential when the Saccharomyces cerevisiae morphogenesis checkpoint is constitutively activated.
Hsl7p plays a central role in the morphogenesis checkpoint triggered when yeast bud formation is impaired and is proposed to function as an arginine methyltransferase. HSL7 is also essential in the absence of the N-terminal tails of histones H3 or H4. The requirement for H3 and H4 tails may indicate a need for their post-translational modification to bypass the morphogenesis ... [more]
