Golgi Glycoprotein 1/GLG1 Antibody [Unconjugated]

Western blot shows lysates of HepG2 human hepatocellular carcinoma cell line and NTera‑2 human testicular embryonic carcinoma cell line. PVDF membrane was probed with 2 µg/mL of Sheep Anti-Human/Mouse/Rat Golgi Glycoprotein 1/GLG1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF7879) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for Golgi Glycoprotein 1/GLG1 at approximately 150 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

Golgi Glycoprotein 1/GLG1 was detected in immersion fixed PC‑12 rat adrenal pheochromocytoma cell line using Sheep Anti-Human/Mouse/Rat Golgi Glycoprotein 1/GLG1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF7879) at 1.7 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Sheep IgG Secondary Antibody (red; Catalog # NL010) and counterstained with DAPI (blue). Specific staining was localized to the Golgi complex. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Golgi Glycoprotein 1/GLG1 was detected in immersion fixed paraffin-embedded sections of human astrocytoma using Sheep Anti-Human/Mouse/Rat Golgi Glycoprotein 1/GLG1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF7879) at 3 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Sheep IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC006). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to Golgi apparatus.

Background

GLG1 (Golgi complex-Localized Glycoprotein 1; also CFR1, E-Selectin ligand-1/ESL-1, MG-160 and Cys-rich FGF receptor) is a 150-160 kDa (reducing; 130 kDa nonreducing) glycoprotein. It is expressed in both Golgi and/or the cell membrane of multiple cell types, including neutrophils (from rodents; not humans), liver stellate cells, neurons, cardiac myocytes, monocytes and bronchial epithelial cells. In the blood, GLG1/ESL-1 collaborates with PSGL-1 to mediate leukocyte binding to endothelial cell surfaces. PSGL-1 initiates leukocyte tethering while GLG1 promotes slow rolling. GLG1 also serves as an intra-Golgi receptor for multiple FGFs, including FGF-1, -2, -4, -18 and possibly -3, and as a component of an unusual latent TGF-beta complex. Mature human GLG1 is an 1150 amino acid (aa) type I transmembrane protein. It contains a 1116 aa extracellular/luminal region (aa 30-1145) plus a short 13 aa cytoplasmic segment. The extracellular region possesses a 16 aa poly-Gln segment followed by 16 Cys-rich repeats (aa 116-1101). There are three potential isoform variants, one of which possess a 24 aa extension at the C‑terminus, a second that couples the aforementioned C‑terminal extension to a deletion of aa 147-157, and a third that contains a 14 aa substitution for aa 685-1179. It is suggested that the longer C‑terminus retains GLG1 in the Golgi, while shorter cytoplasmic segments allow for presentation at the cell membrane. Over aa 1048‑1145, human and mouse are identical in aa sequence.
