NAM8

MRE2, MUD15, L000001147, L000001230, YHR086W
RNA binding protein, component of the U1 snRNP protein; mutants are defective in meiotic recombination and in formation of viable spores, involved in the formation of DSBs through meiosis-specific splicing of REC107 pre-mRNA; Nam8p regulon embraces the meiotic pre-mRNAs of REC107, HFM1, AMA1 SPO22 and PCH2; the putative RNA binding domains RRM2 and RRM3 are required for Nam8p meiotic function

Affinity Capture-MS

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner is identified by mass spectrometric methods.

Composition of yeast snRNPs and snoRNPs in the absence of trimethylguanosine caps reveals nuclear cap binding protein as a gained U1 component implicated in the cold-sensitivity of tgs1{Delta} cells.

Schwer B, Erdjument-Bromage H, Shuman S

Small nuclear and nucleolar RNAs that program pre-mRNA splicing and rRNA processing have a signature 5'-trimethylguanosine (TMG) cap. Whereas the mechanism of TMG synthesis by Tgs1 methyltransferase has been elucidated, we know little about whether or how RNP biogenesis, structure and function are perturbed when TMG caps are missing. Here, we analyzed RNPs isolated by tandem-affinity purification from TGS1 and ... [more]

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.
