Binds to all microtubule populations. Ubiquitous expression throughout development. Expressed during cell division in the syncytial embryo. Expressed in developing photoreceptors of the eye imaginal disk of the third larval stage. In adults, highly expressed in neurons of the brain, concentrated in axons. In the adult ovaries, expression accumulates in the germarium and the polar follicular cells as well as in the oocyte along the microtubule network. Belongs to the MAP Jupiter family. Intron retention.
