Nidogen-1 (also entactin) is a 150 kDa, secreted, monomeric glycoprotein that serves as a major linking component of basement membranes (1-4). It is synthesized as a 1247 amino acid (aa) precursor with a 28 aa signal sequence and a 1219 aa mature protein. The molecule is modular in structure with five distinct regions. There are three globular domains (G1-3) separated by a mucin region and an extended rod-shaped segment (5-7). The N-terminal globular domain (G1) is 200 aa in length and seemingly unrelated to any known motif (8). The mucin region is nearly 160 aa in length and presumably O-glycosylated (2, 8). G2 and G3 are both approximately 300 aa in length. G2 is described as a Nidogen ( beta -barrel) domain, while C-terminal G3 assumes a beta -propeller configuration (1). The 250 aa rod-shaped segment has multiple EGF-like motifs and two thyroglobulin type 1 domains. Functionally, G1 is reported to bind type IV collagen (2, 7). The mucin region contains a short peptide that ligates alpha 3 beta 1 integrins (9, 10). G2 interacts with perlecan, and an RGD motif in the rod-shaped segment serves as a binding site for alpha v beta 3 integrins (9, 10). Finally, G3 is associated with laminin binding (2, 7). As a full-length molecule, the multiple extracellular matrix-binding sites of Nidogen-1 are well positioned to serve as anchor sites for basement membrane molecules. Nidogen-1 also undergoes proteolytic processing by at least two MMPs, MMP-7 and MMP-19 (10, 11). While this destroys the integrity of Nidogen-associated matrices, it also generates peptide fragments that are capable of inducing neutrophil chemotaxis and phagocytosis (10). Nidogen-2 is related to Nidogen-1 (≈ 50% aa identity) and shares many of the same adhesive properties as Nidogen-1 (12). Both bind perlecan plus collagens I and IV. Nidogen‑2, however, does not bind fibulin-1 or 2, and shows only modest interaction with laminin. Thus, although coexpressed, Nidogen-2 serves as only a partial substitute for Nidogen-1 (2, 12). Human Nidogen-1 shares 85% aa sequence identity with both mouse and rat Nidogen-1, and 88% aa sequence identity with canine Nidogen-1.

Detection of Nidogen‑1/Entactin in Human Heart.
Nidogen‑1/Entactin was detected in immersion fixed paraffin-embedded sections of human heart using Mouse Anti-Human Nidogen‑1/Entactin Monoclonal Antibody (Catalog # MAB2570) at 5 µg/ml for 1 hour at room temperature followed by incubation with the HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007) or the Anti-Mouse IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC001). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using VisUCyte Antigen Retrieval Reagent-Basic (Catalog # VCTS021). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to the membrane.

Nidogen-1/Entactin was detected in immersion fixed human mesenchymal stem cells differentiated into chondrocytes using Mouse Anti-Human Nidogen-1/Entactin Monoclonal Antibody (Catalog # MAB2570) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (yellow; NL007) and counterstained with DAPI (blue).

Recombinant Human Nidogen‑1/Entactin (Catalog # 2570-ND) was serially diluted and captured by Mouse Anti-Human Nidogen‑1/Entactin Monoclonal Antibody (Catalog # MAB2570) coated on a Clear Polystyrene Microplate (Catalog # DY990). Goat Anti-Human Nidogen‑1/Entactin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2570) was biotinylated and incubated with the protein captured on the plate. Detection of the standard curve was achieved by incubating Streptavidin-HRP (Catalog # DY998)Detection of Nidogen-1/Entactin by Immunohistochemistry
Zebularine improves wound healing and limbal stem cell phenotype in diabetic organ-cultured corneas via Wnt-5a. (a) Wound healing time was significantly decreased in heptanol-wounded diabetic corneas treated with zebularine (20 µmol/l) vs DMSO (control) (n=4). (b–g) Immunostaining (n=3) showed that zebularine decreased DNMT1 (b) but increased Wnt-5a (c) levels in healed corneas. Zebularine also increased limbal levels of putative stem cell markers, K15 (d) and K17 (e), as well as diabetic markers integrin alpha 3 beta 1 (f) and nidogen-1 (g). Values are mean ± SEM. **p<0.01 vs control (paired t test).
