This family is found primarily in bacterial surface antigens, normally as variable number repeats at the N-terminus. The C-terminus of these proteins is normally represented by Pfam:PF01103. The alignment centres on a -GY- or -GF- motif. Some members of this family are found in the mitochondria. It is predicted to have a mixed alpha/beta secondary structure.	Domain
