COMMD7 (COMM domain containing 7) is a multifunctional scaffold protein that plays crucial roles in cellular signaling and endosomal trafficking. As part of the commander complex, COMMD7 is essential for endosomal recycling of transmembrane cargos 12. The protein functions through multiple mechanisms, including modulation of cullin-RING E3 ubiquitin ligase complexes and association with the NF-κB complex to suppress its transcriptional activity 34. COMMD7 has significant disease relevance, being overexpressed in various cancers including hepatocellular carcinoma, acute myeloid leukemia, and pancreatic ductal adenocarcinoma, where it promotes tumor progression through NF-κB signaling and regulation of factors like CXCL10 5678. The protein also contributes to cisplatin resistance in gastric cancer and affects glucose uptake in beige adipocytes 910. Clinically, high COMMD7 expression correlates with poor prognosis in multiple cancer types and serves as an independent predictor of survival 7. Additionally, COMMD7 shows associations with white cell counts and platelet-dependent thrombus formation, suggesting broader physiological roles beyond cancer 1112.
