PF20857	Immunodominant antigen Pgp3, helical domain	domain

This domain is found in Immunodominant antigen Pgp3, a virulence protein from Chlamydia trachomatis involved in stimulating host immune responses and thought to be required for growth within mammalian cells. Pgp3 consists of globular N- and C-terminal domains (Pfam:PF05475 is the latter) connected by a triple-helical coiled coil (THCC, this entry) [1-3].
