NGL‑3/LRRC4B in Human Brain. NGL‑3/LRRC4B was detected in immersion fixed paraffin-embedded sections of human brain (cerebellum) using Mouse Anti-Human NGL‑3/ LRRC4B Monoclonal Antibody (Catalog # MAB6919) at 15 µg/mL overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Specific staining was localized to the cytoplasm of Purkinje cells. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

NGL-3 (netrin-G ligand-3), also called LRRC4B (Leu-rich repeat/LRR-containing glycoprotein 4B), is a 72 kDa (predicted) post-synaptic adhesion molecule of the LRR protein family. Mature human LRRC4B is a 678 amino acid (aa) type I transmembrane protein with a 541 aa extracellular region (aa 36-576) containing nine LRRs, a C2-type Ig-like domain, and a Thr-rich segment. Over the region used as an immunogen, human LRRC4B shares 97% aa sequence identity with mouse and rat LRRC4B. LRRC4B also shares ~55% aa identity with LRRC4C/NGL-1 and LRRC4/NGL-2, but each recognizes different ligands. LRRC4B recognition of the receptor tyrosine phosphatases LAR/PTPRF, PTPR-d and PTPR-s induces excitatory synapse formation.
