Protein
DSC E3 ubiquitin ligase complex subunit 4
Organism
Schizosaccharomyces pombe (strain 972 / ATCC 24843)
Function
Component of the DSC E3 ubiquitin ligase complex which is required for the sre1 transcriptional activator proteolytic cleavage to release the soluble transcription factor from the membrane in low oxygen or sterol conditions. The complex plays also an important role in the multivesicular body (MVB) pathway and functions in a post-endoplasmic reticulum pathway for protein degradation.
