Representative GFP-tagged basal body proteins in Giardia. Many known basal body proteins, including caltractin (a) and gamma-tubulin complex 3 (b), have been identified in the Giardia genome by homology and confirmed by GFP tagging to localize to the basal bodies. Giardia also has proteins that localize to some basal bodies (c, d) or all basal bodies (e), but lack homology to known basal body proteins. Further, proteins that localize to basal bodies and other structures, including the cell membrane (f), the cytoplasmic axonemes (g), and the median body (h), have also been identified
