- chitin-based extracellular matrix
Any constituent part of a chitin-based noncellular, hardened, or membranous extracellular matrix secreted from the apical surface of an epithelial sheet.
- sequestering of BMP in extracellular matrix
Confining a bone morphogenetic protein (BMP) to the extracellular matrix (ECM), such that it is separated from other components of the signaling pathway, including its cell surface receptor. Bone morphogenetic proteins (BMPs) are secreted as homodimers, non-covalently associated with N-terminal pro-peptides, and are targeted to the extracellular matrix through interaction with matrix proteins.
- perineuronal net
A dense extracellular matrix (ECM) that forms around many neuronal cell bodies and dendrites late in development and is responsible for synaptic stabilization in the adult brain.
- obsolete invadopodium
OBSOLETE. A cell projection that emerges from the ECM-facing surface of a cell, is enriched in actin and associated cytoskeletal proteins, and displays localized proteolytic activity toward the substrate.
- EMILIN complex
Glycoprotein complex of the C1q/TNF superfamily found in the extracellular matrix (ECM) where it is an important component of the elastic fiber system. A homotrimer that will combine to form supramolecular EMILIN structures.
- focal adhesion assembly
The aggregation and bonding together of a set of components to form a focal adhesion, a complex of intracellular signaling and structural proteins that provides a structural link between the internal actin cytoskeleton and the ECM, and also function as a locus of signal transduction activity.
