SNX30 is a sorting nexin family protein that plays important roles in cellular trafficking and autophagy regulation. Together with SNX4, SNX30 is involved in autophagosome assembly, functioning in the regulation of endocytosis and multiple stages of intracellular trafficking 1. SNX30 belongs to the SNX9 subfamily of PX-BAR-containing sorting nexins, which act as membrane tubulators and work with dynamin to form discrete membrane-scission units 1. In disease contexts, SNX30 expression appears to have protective effects. In diabetic kidney disease, higher SNX30 expression correlates positively with estimated glomerular filtration rate and negatively with tubulointerstitial fibrosis 2. The gene has also been identified as conferring protective effects in diabetic retinopathy 3. In lung adenocarcinoma, SNX30 functions as a tumor suppressor by inhibiting cell proliferation and inducing ferroptosis through negative regulation of SETDB1 expression 4. Additionally, SNX30 genetic variants have been associated with increased fasting plasma glucose levels in type 2 diabetes 5, and its promoter methylation is linked to blood pressure regulation and coronary heart disease risk 6.
