BAIT

PSH1

ubiquitin-protein ligase PSH1, YOL054W
E3 ubiquitin ligase targeting centromere-binding protein Cse4p; mediates poyubiquitination and degradation of Cse4p; prevents Cse4p from mislocalizing to euchromatin; ubiquitylation of Cse4p may be antagonized by Scm3p

histone H4, L000000770, YBR009C
Histone H4; core histone protein required for chromatin assembly and chromosome function; one of two identical histone proteins (see also HHF2); contributes to telomeric silencing; N-terminal domain involved in maintaining genomic integrity

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.

Psh1 is an E3 ubiquitin ligase that targets the centromeric histone variant Cse4.

Cse4 is a variant of histone H3 that is incorporated into a single nucleosome at each centromere in budding yeast. We have discovered an E3 ubiquitin ligase, called Psh1, which controls the cellular level of Cse4 via ubiquitylation and proteolysis. The activity of Psh1 is dependent on both its RING and zinc finger domains. We demonstrate the specificity of the ... [more]
