Data Examples
Immunohistochemistry
SMAGP in Human Colon. SMAGP was detected in immersion fixed paraffin-embedded sections of human colon using 15 µg/mL Goat Anti-Human SMAGP Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3959) overnight at 4 °C. Tissue was stained with the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue).

Detection of Human SMAGP by Western Blot. Western blot shows lysates of human lung tissue, PC‑3 human prostate cancer cell line, HT‑29 human colon adenocarcinoma cell line, and MCF‑7 human breast cancer cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human SMAGP Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3959) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for SMAGP at approximately 26 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

Background: SMAGP

SMAGP (small transmembrane and glycosylated protein) is a 25 kDa member of the SMAGP family of proteins. It is expressed on breast, colon and biliary duct epithelium, and likely plays a role in cell-cell adhesion. Human SMAGP is an O-glycosylated, 97 amino acid (aa) type III transmembrane glycoprotein that contains a signal sequenceless N-terminal extracellular region (aa 1-34) plus a 39 aa C-terminal cytoplasmic domain. Over the intra- and extracellular regions combined, human SMAGP is 76% aa identical to mouse SMAGP.

  • Long Name:
    Small Transmembrane and Glycosylated Protein
  • Entrez Gene IDs:
    57228 (Human); 207818 (Mouse); 300236 (Rat)
  • Alternate Names:
    hSMAGP; LOC57228; MGC149453; MGC149454; SMAGP; small cell adhesion glycoprotein; small cell transmembrane and glycosylated protein; Small transmembrane and glycosylated protein; small trans-membrane and glycosylated protein
