Protein Structure

UniProt Annotation

Function

Role in expression of the DDIT3 transcription factor, required for the unfolded-protein response, growth arrest and apoptosis. Has no effect on 28S ribosomal RNA cleavage, unlike the corresponding human protein. {ECO:0000269PubMed:9755171}.

Subcellular Localization

Endoplasmic reticulum membrane {ECO:0000269PubMed:9755171}; Single-pass type I membrane protein {ECO:0000269PubMed:9755171}.
