In eukaryotes this family is predicted to play a role in protein secretion and Golgi organisation [1]. In plants this family includes Swiss:A9X6Y0, which is involved in water permeability in the cuticles of fruit [2]. Swiss:P54797 has been found to be expressed during early embryogenesis in mice [3]. This protein contains a conserved NRDE motif. This gene has been characterised in Drosophila melanogaster and named as transport and Golgi organisation 2, hence the name Tango2.
