背景 | Neuroglycan C (NGC; also CSPG5 and CALEB) is a 120‑150 kDa type I transmembrane glycoprotein and member of the neuregulin family of proteins (1, 2). Depending on its expression profile, NGC may be a glycoprotein of 120 kDa, or a chondroitin sulfate (CS) proteoglycan of 150 kDa (2, 3). Human NGC is synthesized as a 566 amino acid (aa) precursor that contains a 30 aa signal sequence, a 393 aa extracellular domain (ECD), a 21 aa transmembrane segment, and a 122 aa cytoplasmic region. The ECD contains one CS attachment domain (aa 34‑272), with CS attachment at Ser117, one EGF‑like domain (aa 371‑413), two potential sites for N‑linked glycosylation, and twelve potential sites for O‑linked glycosylation (4). Splicing variants produce three isoforms for human NGC. Isoform 1 is the long form. Isoform 2 has a deletion of aa 487‑513, while isoform 3 has an alternative start site at Met139 and the same deletion. Phosphorylation likely occurs at Ser249, and proteolysis generates a 75 kDa soluble fragment (5). Over aa 31‑420, human NGC shares 84% aa identity with mouse NGC. NGC is expressed in nervous tissue and is found on retinal ganglion cells, cerebellar Purkinje cells and hippocampal neurons (6). NGC may function as a growth and differentiation factor involved in neuritogenesis. One study shows that the recombinant ectodomain of NGC core protein enhances neurite outgrowth from rat neocortical neurons in culture via phosphatidylinositol 3‑kinase and protein kinase C signaling pathways (7). Another study states that NGC is a novel component of midkine receptors, a heparin‑binding growth factor that promotes cell attachment and process extension in oligodendroglial precursor‑like cells (3). NGC also acts as a growth factor by directly binding ERbB3 tyrosine kinase and transactivating ErbB2 (1). |

Detection of Human Neuroglycan C/CSPG5 by Western Blot. Western blot shows lysates of SH‑SY5Y human neuroblastoma cell line. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Human Neuroglycan C/CSPG5 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5685) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). Specific bands were detected for Neuroglycan C/CSPG5 at approximately 120 and 150 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8. |
