This entry represents an alpha-beta plait domain from a group of fungal TMEM16 family of proteins, also known as anoctamins, including SwissProt:Q4WA18 from Aspergillus fumigatus and ist2 from S.pombe. Proteins in this entry operate as Ca2+-activated lipid scramblases [1-3]. This domain may play a role in dimerisation, although its precise function is uncertain.	Domain
