This domain is found in pore-forming toxin stonustoxin (SNTX), a lethal venom found in Synanceia horrida. Because of the thioredoxin-like nature of the domain, it is referred to as the THX domain. The THX domain is comprised of a five-stranded beta-sheet and shares greatest structural similarity with Saccharomyces cerevisiae mitochondrial THX3. It is thought that THX domain plays a purely structural role [1].	Domain
A	PF21109	Stonustoxin helical domain (Stonustoxin_helical)	Stonustoxin helical domain	This entry represents the stonustoxin helical domain. Stonustoxin is a large pore forming toxin found in stonefish. This entry contains stonustoxin as well as a variety of other toxin proteins such as veruccotoxin.	Domain
