Abstract

Using monoclonal antibody against the 45 kDa postsynaptic density protein, we isolated a novel isoform of Homer/vesl. The NH2-terminal region containing a PDZ domain of this protein is identical to that of Homer/vesl, and the COOH-terminal region containing unique leucine zippers shows self-multimerization. We named this protein PSD-Zip45. In addition to specific binding of PSD-Zip45 mediated by a PDZ domain to the metabotropic glutamate receptors 1alpha or 5, the distribution of PSD-Zip45 transcripts is highly consistent with that of metabotropic glutamate receptor transcripts. The PSD-Zip45 is, therefore, the first candidate as receptor anchoring proteins containing leucine zipper motifs in the central nervous system.
