HST1

histone deacetylase HST1, L000000826, YOL068C
NAD(+)-dependent histone deacetylase; essential subunit of the Sum1p/Rfm1p/Hst1p complex required for ORC-dependent silencing and mitotic repression; non-essential subunit of the Set3C deacetylase complex; involved in telomere maintenance; HST1 has a paralog, SIR2, that arose from the whole genome duplication

ORC2

RRR1, SIR5, origin recognition complex subunit 2, L000001776, YBR060C
Subunit of the origin recognition complex (ORC); ORC directs DNA replication by binding to replication origins and is also involved in transcriptional silencing; interacts with Spp1p and with trimethylated histone H3; phosphorylated by Cdc28p
Saccharomyces cerevisiae (S288c)

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.

Control of replication initiation by the Sum1/Rfm1/Hst1 histone deacetylase.

Weber JM, Irlbacher H, Ehrenhofer-Murray AE

BACKGROUND: Replication initiation at origins of replication in the yeast genome takes place on chromatin as a template, raising the question how histone modifications, for instance histone acetylation, influence origin firing. Initiation requires binding of the replication initiator, the Origin Recognition Complex (ORC), to a consensus sequence within origins. In addition, other proteins bind to recognition sites in the vicinity ... [more]
