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

RAD52

recombinase RAD52, L000001572, YML032C
Protein that stimulates strand exchange; stimulates strand exchange by facilitating Rad51p binding to single-stranded DNA; anneals complementary single-stranded DNA; involved in the repair of double-strand breaks in DNA during vegetative growth and meiosis and UV induced sister chromatid recombination
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.

Lsm1 promotes genomic stability by controlling histone mRNA decay.

Herrero AB, Moreno S

Lsm1 forms part of a cytoplasmic protein complex, Lsm1-7-Pat1, involved in the degradation of mRNAs. Here, we show that Lsm1 has an important role in promoting genomic stability in Saccharomyces cerevisiae. Budding yeast cells lacking Lsm1 are defective in recovery from replication-fork stalling and show DNA damage sensitivity. Here, we identify histone mRNAs as substrates of the Lsm1-7-Pat1 complex in ... [more]
