Gasdermin-A3 (Gsdma3)

May play a role in the transition from catagen to telogen in the conclusion of hair follicle morphogenesis (PubMed:15475261). May promote pyroptosis (PubMed:26375003, PubMed:27281216).

Upon cleavage in vitro of genetically designed Gsdma3, the published N-terminal moiety binds to membrane inner leaflet lipids, including bisphosphorylated phosphatidylinositols, such as phosphatidylinositol (4,5)-bisphosphate, as well as phosphatidylinositol (3,4,5)-bisphosphate, and much more weakly to monophosphorylated phosphatidylinositols. Homooligomerizes inside the membrane and forms pores of 10 -15 nanometers (nm) of inner diameter, triggering pyroptosis.
