Application: All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry. The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link.

Biochem Physiol Actions: In human DLG3 (disks large homolog 3) encodes for synapse-associated protein 102 (SAP102) that belongs to the guanylate kinase protein family. It is found to be expressed during early brain development and is present to the postsynaptic density of excitatory synapses. Structurally, it is composed of three amino-terminal PDZ (PSD95, Dlg1, zo-1) domains, an Src homology domain, and a carboxyl-terminal guanylate kinase domain. The PDZ domains participates in mediating protein-protein interactions and also helps in binding to the short amino acid motifs at the carboxyl termini of interacting proteins. It plays a positive role in clustering of NMDA (N-methyl-D-aspartate) receptors at excitatory synapses as well as it negatively regulate cell proliferation through interaction with the C-terminal region of the polyposis coli tumor suppressor protein. Mutation in DLG3 gene causes a heterogeneous disorder: nonsyndromic X-linked mental retardation.
