Predicted to enable metalloendopeptidase activity. Predicted to be involved in membrane protein intracellular domain proteolysis; positive regulation of transcription from RNA polymerase II promoter in response to endoplasmic reticulum stress; and regulation of response to endoplasmic reticulum stress. Predicted to be located in cytoplasm. Human ortholog(s) of this gene implicated in X-linked recessive disease (multiple). Is an ortholog of human MBTPS2 (membrane bound transcription factor peptidase, site 2).
