This domain is found at the N-terminal end of Small heat shock protein Tsp36 from the parasitic flatworm Taenia saginata and similar proteins from worms. Tsp36 is organised into two alpha-crystallin domains, two repeat segments on the N-terminal side, a linker region, and a long N-terminal segment of about 80 residues (this entry). This domain consists of a series of helices with sharp turns between them marked by prolines [1].	Domain
