These sequences comprise a paralogous family of hypothetical proteins in Brassicaceae. Length heterogeneity within the family is attributable partly to a 21-residue repeat present in from zero to three tandem copies. One member of the family, protein MS5, has been shown to be important for progression of meiosis during early prophase and is essential for pairing of homologues. It is preferentially expressed in reproductive organs [ 1 ].

1. MS5 mediates early meiotic progression and its natural variants may have applications for hybrid production in Brassica napus. Plant Cell
