RLYB331
RLYB331 (KY1066) is a is a monoclonal antibody targeting Matriptase-2 (TMPRSS6). RLYB331 binds to the serine protease active site of matriptase-2, blocking protease activity to increase hepcidin expression. RLYB331 reduces iron overload, inhibits α-aggregates, reduces ROS, inhibits apoptosis, and enhances erythroid differentiation. RLYB331 ameliorates ineffective erythropoiesis in β-thalassemic mouse models. RLYB331 can be used for the research of β-thalassemia.

Biological Activity
Human
RLYB331 (10 mg/kg; i.p.; single dose) increases hepcidin expression via enhanced Bmp/Smad signaling in healthy C57BL/6 mice[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
