AGFG1 (ArfGAP with FG repeats 1) is a protein involved in intracellular vesicle trafficking and cholesterol metabolism with emerging roles in cancer progression. Primary functions include regulation of vesicle docking and fusion during acrosome biogenesis, and participation in RNA trafficking and export 1. The protein interacts with CAV1 to relocate cholesterol within cells, thereby modulating intracellular cholesterol biosynthesis 1. In pancreatic ductal adenocarcinoma, AGFG1 upregulation disrupts cholesterol homeostasis to enhance cholesterol biosynthesis, promoting tumor cell proliferation 1. Circular RNA variants of AGFG1 (circAGFG1) function as microRNA sponges, sequestering miR-653-5p in breast cancer and miR-497-5p in esophageal squamous cell carcinoma, thereby promoting malignant cell behaviors including proliferation, invasion, and metabolic reprogramming 23. Additionally, genetic variants in AGFG1 are associated with airway hyperresponsiveness severity in asthma, suggesting a role in airway smooth muscle regulation 4. Clinically, AGFG1 expression correlates with poor prognosis in PDAC, positioning it as a potential therapeutic target for cholesterol metabolism-based cancer interventions. The multiple disease associations and emerging understanding of its metabolic functions warrant further investigation into AGFG1-targeted therapies.
