IQG1
CYK1, L000004180, YPL242C
Essential protein required for determination of budding pattern; promotes localization of axial markers Bud4p and Cdc12p and functionally interacts with Sec3p, localizes to the contractile ring during anaphase, member of the IQGAP family; relocalizes from bud neck to cytoplasm upon DNA replication stress

DMA1
CHF1, ubiquitin-conjugating protein DMA1, S000029719, YHR115C
Ubiquitin-protein ligase (E3); controls septin dynamics, spindle position checkpoint (SPOC) with ligase Dma2p by regulating recruitment of Elm1p to bud neck; regulates levels of eIF2 subunit Gcd11p, as well as abundance, localization, and ubiquitination of Cdk inhibitory kinase Swe1p; ubiquitinates cyclin Pcl1p; ortholog of human RNF8, similar to human Chfr; contains FHA, RING fingers; DMA1 has a paralog, DMA2, that arose from the whole genome duplication

Dosage Lethality
A genetic interaction is inferred when over expression or increased dosage of one gene causes lethality in a strain that is mutated or deleted for another gene.
Publication
Saccharomyces cerevisiae Dma proteins participate in cytokinesis by controlling two different pathways.
Cytokinesis completion in the budding yeast S. cerevisiae is driven by tightly regulated pathways, leading to actomyosin ring contraction coupled to plasma membrane constriction and to centripetal growth of the primary septum, respectively. These pathways can partially substitute for each other, but their concomitant inactivation leads to cytokinesis block and cell death. Here we show that both the lack of ... [more]

Throughput
- Low Throughput
Ontology Terms
- phenotype: septum formation (APO:0000221) [abnormal (APO:0000002)]
- phenotype: inviable (APO:0000112)
Additional Notes
- Analysis of the terminal phenotype indicated that primary septum formation was abnormal
- GAL-driven overexpression of DMA1 caused lethality of hof1 mutant at 25 deg C
