DSL1

RNS1, L000004950, YNL258C
Peripheral membrane protein needed for Golgi-to-ER retrograde traffic; mediates Sey1p-independent homotypic ER fusion; forms a complex with Sec39p and Tip20p that interacts with ER SNAREs Sec20p and Use1p; component of the ER target site that interacts with coatomer; interacts with Cin5p; similar to the fly and human ZW10 gene

CIK3, NRD2, putative DNA/RNA helicase SEN1, L000001862, YLR430W
Presumed helicase and subunit of the Nrd1 complex (Nrd1p-Nab3p-Sen1p); complex interacts with the exosome to mediate 3' end formation of some mRNAs, snRNAs, snoRNAs, and CUTs; has a separate role in coordinating DNA replication with transcription, by associating with moving replication forks and preventing errors that occur when forks encounter transcribed regions; homolog of Senataxin, which is implicated in Ataxia-Oculomotor Apraxia 2 and a dominant form of ALS

Negative Genetic

Mutations/deletions in separate genes, each of which alone causes a minimal phenotype, but when combined in the same cell results in a more severe fitness defect or lethality under a given condition. This term is reserved for high or low throughput studies with scores.

ER-associated retrograde SNAREs and the Dsl1 complex mediate an alternative, Sey1p-independent homotypic ER fusion pathway.

Rogers JV, McMahon C, Baryshnikova A, Hughson FM, Rose MD

The peripheral endoplasmic reticulum (ER) network is dynamically maintained by homotypic (ER-ER) fusion. In Saccharomyces cerevisiae, the dynamin-like GTPase Sey1p can mediate ER-ER fusion, but sey1Δ cells have no growth defect and only slightly perturbed ER structure. Recent work suggested that ER-localized soluble N-ethylmaleimide-sensitive factor attachment protein receptors (SNAREs) mediate a Sey1p-independent ER-ER fusion pathway. However, an alternative explanation - ... [more]
