Nidogen, G2 domain; Nidogen is an important component of the basement membrane, an extracellular sheet-like matrix. Nidogen is a multifunctional protein that interacts with many other basement membrane proteins, like collagen, perlecan, lamin, and has a potential role in the assembly and connection of networks. Nidogen consists of 3 globular domains (G1-G3), G3 is the lamin-binding domain, while G2 binds collagen IV and perlecan. Also found in hemicentin, a protein which functions at various cell-cell and cell-matrix junctions and might assist in refining broad regions of cell contact into oriented, line-shaped junctions. Nidogen G2 consists of an N-terminal EGF-like domain (excluded from this alignment model) and an 11-stranded beta-barrel with a central helix, a topology that exhibits high structural similarity to the green flourescent proteins of Cnidaria.
No pairwise interactions are available for this conserved domain.
Tips:  If you've navigated here from a protein, hovering over a position on the weblogo will display the corresponding protein position for that domain position. The histograms below the weblogo indicate mutations found on the domain. Red is for disease (OMIM) and blue is for SNPs. Functional Features are displayed as orange boxes under the histograms. You can choose which features are displayed in the box below. Range on the Protein: Protein ID Protein Position Domain Position:
