Ready-to-use ELISA kits are available for the detection of InaD-like (Drosophila), an alias of the protein, PATJ crumbs cell polarity complex component. The official gene symbol is PATJ. The protein has a mass of 196.4 kDa and length of 1801 residues. It may be known by other names, including: inactivation-no-afterpotential D-like, inactivation no after-potential D-like protein, channel-interacting PDZ domain protein, PDZ domain protein, PALS1-associated tight junction protein, and inaD-like protein, and Cipp.
