UBP10

DOT4, L000004391, L000004588, YNL186W
Ubiquitin-specific protease, deubiquitinates Ub-protein moieties; interacts with proteins that function in rRNA production and ribosome biogenesis; stabilizes Rpa190p, the largest subunit of RNAP I, by mediating its deubiquitination; controls PCNA deubiquitylation; may regulate silencing by acting on Sir4p; involved in posttranscriptionally regulating Gap1p and possibly other transporters; localized to the nucleolus; human USP36 is a functional analog of Ubp10p

Synthetic Rescue

A genetic interaction is inferred when mutations or deletions of one gene rescues the lethality or growth defect of a strain mutated or deleted for another gene.

Ubiquitination of histone H2B regulates chromatin dynamics by enhancing nucleosome stability.

Chandrasekharan MB, Huang F, Sun ZW

The mechanism by which ubiquitination of histone H2B (H2Bub1) regulates H3-K4 and -K79 methylation and the histone H2A-H2B chaperone Spt16-mediated nucleosome dynamics during transcription is not fully understood. Upon investigating the effect of H2Bub1 on chromatin structure, we find that contrary to the supposed role for H2Bub1 in opening up chromatin, it is important for nucleosome stability. First, we show ... [more]

Additional Notes

  • (ubp8 ubp10 H2B-K123R triple mutant)
  • The slow growth defect of ubp8 ubp10 double mutants can be rescued by eliminating H2B (HTB1,HTB2) ubiquitination through the mutation of the site of ubiquitination (H2B-K123R).

Biochemical Activity
Biochemical Activity

An interaction is inferred from the biochemical effect of one protein upon another, for example, GTP-GDP exchange activity or phosphorylation of a substrate by a kinase. The bait protein executes the activity on the substrate hit protein. A Modification value is recorded for interactions of this type with the possible values Phosphorylation, Ubiquitination, Sumoylation, Dephosphorylation, Methylation, Prenylation, Acetylation, Deubiquitination, Proteolytic Processing, Glucosylation, Nedd(Rub1)ylation, Deacetylation, No Modification, Demethylation.
