LPH encompasses four homologous domains, which presumably have evolved from two subsequent duplications of one ancestral gene, domain organization, overview. The profragment, LPHalpha, comprises homologous domains I and II and functions as an intramolecular chaperone in the context of the brush-border LPHbeta region of LPH. Inter-relationship between homologous domains III and IV of LPHbeta implication in the overall structure, function, and trafficking of LPH, overview. Isolated homologous domain III is transport-competent per se and sorted to the apical membrane in polarized cells. Nevertheless, it neither dimerizes nor acquires complete phlorizin hydrolase activity |
