9.B.431. The Uncharacterized Protein of ~110 aas and 1 TMS (UF-1) Family The proteins of this family are of ~100 - 124 aas in length and have 1 TMS. Although one is annotated as a gasdermin, the others are viral or bacterial or archaeal proteins of unknown function.
Examples:
TC#	Name	Organismal Type	Example
