The name PDZ derives from the first three proteins in which these domains were identified: PSD-95 (a 95 kDa protein involved in signaling at the post-synaptic density), DLG (the Drosophila melanogaster Discs Large protein) and ZO-1 (the zonula occludens 1 protein involved in maintenance of epithelial polarity)1,2.MAGUKs are scaffolding proteins that comprise several modular protein binding motifs including one or more PDZ domains, a Src homology 3 (SH3) domain, and a catalytically inactive guanylate kinase-like domain1,2.The multidomain nature of PDZ-containing proteins enables them to interact with multiple binding partners and hence organize larger signaling protein complexes.Indeed, Chapsyn 110 has been shown to participate in the postsynaptic density, a dedicated structure formed in postsynaptic nerve terminals that includes a specialized assembly of ion channels, receptors and signaling molecules that are involved in information processing and the modulation of synaptic plasticity1,2.\u003c\/p\u003e  \u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e \u003cul\u003e   \u003cli\u003eComparing target expression across perturbations, genotypes, or treatment conditions.\u003c\/li\u003e   \u003cli\u003eInterpreting localization shifts alongside pathway or phenotypic readouts.\u003c\/li\u003e   \u003cli\u003eUsing orthogonal controls (KO\/KD, peptide competition, isotype concepts) to support conclusions.\u003c\/li\u003e \u003c\/ul\u003e  \u003ch2\u003eCommon research applications\u003c\/h2\u003e \u003cul\u003e   \u003cli\u003eWestern blot (WB): compare target abundance\/size across lysates and conditions;
