COMMD10 is a scaffold protein within the Commander complex, which comprises the CCC subcomplex (containing COMMD1–COMMD10 plus CCDC22 and CCDC93) and the Retriever subcomplex. The Commander complex is essential for endosomal recycling of transmembrane cargos 1. COMMD10 also modulates cullin-RING E3 ubiquitin ligase activity and suppresses NF-κB signaling by preventing p65 nuclear translocation and inhibiting IκBα ubiquitination 2. In hepatocellular carcinoma (HCC), COMMD10 acts as a tumor suppressor by enhancing ferroptosis and radiosensitivity through disruption of copper–iron homeostasis and inhibition of the HIF1α/ceruloplasmin feedback loop 3. COMMD10 expression is reduced in HCC tissues and suppresses cell proliferation while inducing apoptosis 2. Similarly, in gastric adenocarcinoma, elevated COMMD10 expression correlates with poorer overall survival and is linked to m6A-mediated RNA modifications 4. In colorectal cancer, FMNL2-mediated degradation of COMMD10 activates NF-κB signaling, promoting invasion and metastasis 5. During inflammation, COMMD10 restrains inflammasome activity in Ly6Chi monocytes, limiting systemic cytokine production and colonic inflammation in sepsis and inflammatory bowel disease models 6. Embryonic development requires COMMD10; homozygous knockout mice die by embryonic day 8.5 due to neural crest failure 7.
