P{NZ} is an enhancer trap construct that encodes a lacZ reporter protein that is targeted to the minus-end of microtubules. The enhancer trap sequence is at the 5' end of the construct and consists of the weak P\T promoter upstream of a coding sequence 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.
