Biological Activity: PSMα3 is an inhibitor of NF-κB p65 and p38 MAPK. PSMα3 forms membrane pores and binds to residues of human insulin B chain to inhibit insulin aggregation. PSMα3 forms α-type amyloid-like fibrils to exert cytotoxic effects, and acts as a functional amyloid virulence determinant of Staphylococcus aureus. PSMα3 is applicable to research related to spondyloarthritis, rheumatoid arthritis, insulin-derived amyloidosis, and Staphylococcus aureus infection[1][2][3].
