HAPLN4 in Human Brain. HAPLN4 was detected in immersion fixed paraffin-embedded sections of human brain (caudate nucleus) using 3 µg/mL Goat Anti-Human HAPLN4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4085) 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 with the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue).

HAPLN4 (hyaluronan and proteoglycan link protein 4; also Bral2) is a 40-42 kDa secreted member of the Link module superfamily. It is secreted by select neurons, particularly of the cerebellum, where it participates in ECM stability. Here it may link hyaluronic acid with resident proteoglycans. Mature HAPLN4 is 383 amino acids (aa) in length. It contains one lg-like C2-type domain (aa 46-161) and two link domains (aa 163-365). One potential alternate start site exists 36 aa upstream of the standard start site. Human and mouse HAPLN4 share 91% aa sequence identity.
