Nidogen‑1/Entactin antibody in Human Heart by Immunohistochemistry (IHC-P).

Nidogen‑1/Entactin in Human Heart.

Nidogen‑1/Entactin was detected in immersion fixed paraffin-embedded sections of human heart using Goat Anti-Human Nidogen‑1/Entactin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2570) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific labeling was localized to the sarcolemma of cardiomyocytes. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Degradation of nidogen-1 by PSA.PSA cleaved both mouse nidogen-1 in Matrigel and human recombinant nidogen-1. Mass spectrometry analysis identified nidogen-1 in the silver stained gel bands (arrows, left panel). Nidogen-1 bands of 140 kDa (A) and 110 kDa (B) disappeared and fragments of 90 kDa (C) and 55 kDa (D) appeared after 48 h incubation of diluted Matrigel with PSA at 37°C. Nidogen-1 cleavage by PSA in Matrigel was visualized by Western blotting with anti-nidogen-1 polyclonal antibody (middle panel). PSA (1 µM) cleaved recombinant human nidogen-1 (0.5 µM) into two fragments 85 kDa (arrow with *) and 55 kDa (arrow with **) during 20 h incubation at 37°C (right panel).

Cleavage of protein substrates by PSA.(A) Characterization of the proteolytic activity of PSA (0.2 µM) during 22 h incubation towards different protein substrates (1 µM each, except 0.5 µM semenogelin I) by SDS-PAGE and silver staining. Approximate molecular weights of the proteins are: PSA (28 kDa), semenogelin I (50 kDa), semenogelin II (63 kDa), fibronectin (220 kDa), galectin-3 (26 kDa), IGFBP-3 (30 kDa) and nidogen-1 (130 kDa). The lanes in which ∼50% of the proteins were cleaved are bordered. (B) 1 µM MMP-3 (22 kDa), but not PSA, cleaved 1 µM plasminogen (88 kDa). Also 0.5 M fibronectin was incubated with 1 µM PSA as a control (SDS-PAGE with silver staining).

Background: Nidogen-1/Entactin

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.
