Asymmetric/Biological Unit(hide GO term definitions)

Chain A (SCX8_MESMA | P54135)

molecular function
	GO:0008200	ion channel inhibitor activity	Stops, prevents, or reduces the activity of an ion channel.
biological process
	GO:0006952	defense response	Reactions, triggered in response to the presence of a foreign body or the occurrence of an injury, which result in restriction of damage to the organism attacked or prevention/recovery from the infection caused by the attack.
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.
