DDIT3
DDIT3 (CHOP, GADD153) is a human 12q13.3 gene encoding a C/EBP-family bZIP stress-response transcription factor that promotes apoptosis during ER stress and forms FUS or EWSR1 fusion oncogenes diagnostic of myxoid liposarcoma.
DDIT4
DDIT4 (REDD1, RTP801, Dig2) is a human chromosome 10q22.1 stress-responsive gene encoding a 232-amino-acid inhibitor of mTORC1 via the TSC1/TSC2-RHEB axis, induced by hypoxia and DNA damage and implicated in cancer prognosis, diabetes, and venous malformation.
