UASt regulatory sequences drive expression of a fusion protein that is composed of amino acids 1-320 of nod (includes the globular head motor domain), the N-terminal half of the Khc coiled-coil domain (residues 334-606) and lacZ.
This construct (where the Khc head domain has been replaced by the nod head domain) is a marker for minus ends of microtubules, and localizes to nuclei in developing facets.
