Domain

Aspartic peptidase, DDI1-type (IPR019103)

Short name: Peptidase_aspartic_DDI1-type

Domain relationships

Description

This domain is found in eukaryotic aspartyl protease DDI1 (DNA Damage Inducible protein 1; MEROPS identifier A28.001). The remarkable structural similarity between this central domain of DDI1 and the retroviral proteases suggests that DDI1 functions proteolytically during regulated protein turnover [PMID: 17010377, PMID: 15964793]. DDI1 has been shown to activate an endoplasmic-reticulum isoform of the transcription factor SKN-1 in Caenorhabditis elegans when the proteasome is dysfunctional [PMID: 27528192]. DDI1 also has an amino-terminal ubiquitin-like domain and/or a UBA (ubiquitin-associated) domain [PMID: 27646017].
