Abstract / Description of output

The PDZ domain gained its name from the three proteins that were first seen to have homology by virtue of these domains, the mammalian postsynaptic density protein, PSD-95, the Drosophila discs-large septate junction protein, DLG, and the mammalian epithelial tight-junction protein zona occludens, ZO-1. Over 50 PDZ domain-containing genes have been recognized so far from almost any organism subjected to sequencing, including mammals, nematodes, yeast, plants, and bacteria. The domain consists of an approximately 90-amino-acid-residue unit, which is often repeated in the protein. The majority of residues form a conserved spatial structure while a few amino acids in critical positions confer protein binding specificity. A subgroup of PDZ domains have been shown to recognize a short carboxy-terminal amino acid motif, T/SXV (Ser/Thr-X-Val-COO-), where X is any amino acid. We have identified and completely sequenced a gene, Mpdz, that encodes a mouse protein containing 13 such domains. We have also mapped the gene to a series of overlapping deletions on mouse chromosome 4 and can therefore determine that its function is not essential for embryonic development or neonatal survival.
