Chain A (TXMG4_MACGS | P83560)

molecular function
	GO:0019871	sodium channel inhibitor activity	Stops, prevents, or reduces the activity of a sodium channel.
biological process
	GO:0009405	pathogenesis	The set of specific processes that generate the ability of an organism to induce an abnormal, generally detrimental state in another organism.
cellular component
	GO:0005576	extracellular region	The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
