Chain A (SLAA_PROFL | Q8AV97)

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.

Chain B (SLAB_PROFL | Q8AV98)

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.
