Spindlin (Spin) is a novel maternal transcript present in the unfertilised egg and early embryo [1]. The Y-linked spermiogenesis -specific transcript (Ssty) is also expressed during gametogenesis and forms part of this Pfam family. Members of this family contain three copies of this 50 residue repeat. The repeat is predicted to contain four beta strands.	Domain
