Summary: Enables ubiquitin-protein transferase activity. Involved in cellular response to unfolded protein; cytoplasm protein quality control by the ubiquitin-proteasome system; and protein polyubiquitination. Located in cytoplasm. Part of MUB1-RAD6-UBR2 ubiquitin ligase complex. Orthologous to several human genes including UBR2 (ubiquitin protein ligase E3 component n-recognin 2).

Altogether, these data indicate that the absence of R37 methylation on Cse4 reduces the recruitment of kinetochore proteins to centromeric chromatin, and that this can be compensated for by stabilizing the outer kinetochore protein Dsn1 via the ubiquitin ligase complex Ubr2/Mub1.
