What determines the tissue-specific role of EMP1 in ER stress regulation across different cell types?

OPEN

While EMP1 is shown to regulate ER stress in HSCs through CERS2 interaction, it's unclear whether this mechanism operates similarly in neurons or other cells prone to ER stress-related degeneration. This knowledge gap limits understanding of EMP1's broader therapeutic potential. Gap type: open_question Source paper: EMP1 safeguards hematopoietic stem cells by suppressing sphingolipid metabolism and alleviating endoplasmic reticulum stress. (2025, Nat Commun, PMID:40624017)
