Detection of Human CD300g/Nepmucin by Western Blot.
Western blot shows lysates of HepG2 human hepatocellular carcinoma cell line and THP‑1 human acute monocytic leukemia cell line. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Human CD300g/Nepmucin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5328) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). Specific bands were detected for CD300g/Nepmucin at approximately 75-95 kDa and 37 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

Nepmucin (A mucin not expressed in Peyer's Patches; also CD300g, CLM9, and TREM4) is a 75-95 kDa, O-glycosylated member of the CD300 family of molecules. It is expressed on capillary endothelium, and appears to serve multiple functions. Via a mucin domain, it binds lymphocyte L-selectin, contributing to cell migration. It also binds immunoglobulins A and M, perhaps mediating transendothelial transport. Mature human nepmucin is a 314 amino acid (aa ) type I transmembrane glycoprotein. It contains one V-type Ig-like domain (aa 19-121), a mucin stalk (aa 137-237), and a cytoplasmic region (aa 269-332). There are at least two isoform variants of nepmucin. Each shows a deletion of aa 128-212, accompanied by either a 23 aa, or 12 aa substitution for aa 296-332. Over aa 19-249, human nepmucin shares 51% aa identity with mouse nepmucin.
