LSM1

SPB8, L000004427, YJL124C
Lsm (Like Sm) protein; forms heteroheptameric complex (with Lsm2p, Lsm3p, Lsm4p, Lsm5p, Lsm6p, and Lsm7p) involved in degradation of cytoplasmic mRNAs; also enters the nucleus and positively regulates transcription initiation; unlike most Sm-like proteins, Lsm1p requires both its SM-domain and C-terminal domain for RNA-binding; binds to mRNAs under glucose starvation, most often in the 3' UTR; forms cytoplasmic foci upon DNA replication stress
Saccharomyces cerevisiae (S288c)
PREY

SRS2

HPR5, DNA helicase SRS2, RADH1, RADH, L000000809, L000001578, YJL092W
DNA helicase and DNA-dependent ATPase; involved in DNA repair and checkpoint recovery, needed for proper timing of commitment to meiotic recombination and transition from Meiosis I to II; blocks trinucleotide repeat expansion; affects genome stability; disassembles Rad51p nucleoprotein filaments during meiotic recombination; functional homolog of human RTEL1
Saccharomyces cerevisiae (S288c)

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.

Srs2 overexpression reveals a helicase-independent role at replication forks that requires diverse cell functions.

Leon Ortiz AM, Reid RJ, Dittmar JC, Rothstein R, Nicolas A

Srs2 is a 3'-5' DNA helicase that regulates many aspects of DNA metabolism in Saccharomyces cerevisiae. It is best known for its ability to counteract homologous recombination by dismantling Rad51 filaments, but is also involved in checkpoint activation, adaptation and recovery, and in resolution of late recombination intermediates. To further address its biological roles and uncover new genetic interactions, we ... [more]

Throughput

  • High Throughput

Ontology Terms

  • inviable (APO:0000112)
  • colony size (APO:0000063)

Additional Notes

  • High Throughput: Three synthetic dosage lethality screens were carried out to identify genes required for cell viability upon overexpression of SRS2 and/or its helicase mutants srs2-K41A and srs2-K41R.
