Caspr1 in Human Brain. Caspr1 was detected in immersion fixed paraffin-embedded sections of human brain using Sheep Anti-Human Caspr1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF7548) at 5 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Sheep HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS019) and counterstained with hematoxylin (blue). Specific staining was localized to paranodal axonal regions in neurons. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Background: Caspr1
CASPR1 (Contactin-ASsociated PRotein-1; also Neurexin-4 and p190) is a 180-195 kDa member of the neurexin family of proteins. It is expressed on both axons and dendrites of neurons, and likely serves the critical function of directing the movement of low MW contactin, AMPA receptors, and Na+ plus K+ channels to appropriate sites on the cell membrane. This indicates participation in key processes such as myelination and excitatory neurotransmission. Mature human CASRP1 is a 1365 amino acid (aa) type I transmembrane protein. It contains a 1264 aa extracellular region (aa 20-1283) plus an 80 aa cytoplasmic domain. The extracellular region is highly modular, possessing one discoidin (carbohydrate-binding) domain (aa 24-158), four laminin G-like domains (aa 203-513, 813-956 and 1088-1250), two EGF-like domains (aa 540-577 and 957-996) and one fibrinogen C-terminal globular regions (aa 576-795). There is one potential alternative start site at Met507. Over aa 20-1280, human CASPR1 shares 94% aa sequence identity with mouse CASPR1.
