Summary
This study reviews recent advances in basement membrane collagens, focusing on multiplexins and skin membrane collagens. It explores ectodomain shedding mechanisms and the biological roles of these collagen fragments.
Area of Science:
- Biochemistry
- Molecular Biology
- Cell Biology
Context:
- Collagens are crucial extracellular matrix proteins.
- The collagen superfamily comprises 27 members with diverse structures and functions.
- Previous reviews covered fibrillar collagens and FACITs.
Purpose:
- To report recent advances on basement membrane-associated collagens.
- To focus on the multiplexin family (collagens XV and XVIII) and skin membrane collagens (collagens XIII and XVII).
- To discuss ectodomain shedding mechanisms and the biological roles of shed collagen domains.
Summary:
- This paper details recent findings on collagens linked to basement membranes.
- It specifically examines the multiplexin family (collagens XV, XVIII) and membrane collagens in skin (collagens XIII, XVII).
- The study investigates ectodomain shedding from cell membranes and the functions of the released fragments, including matricryptins/matrikines.
Impact:
- Enhances understanding of collagen structure-function relationships.
- Provides insights into the biological roles of specific collagen types and their fragments.
- Contributes to the knowledge of extracellular matrix dynamics and cell signaling.

01:05Type IV Collagen of Basal Lamina
Type IV collagen is a 400 nm long, network-forming collagen that acts as a barrier between the epithelial and endothelial cells. Type IV collagen forms the backbone of the basement membrane by scaffolding with laminin, entactin, proteoglycans, and fibronectin. Apart from rendering structural support to the basement membrane, it also helps entail signaling potentials necessary for both pathological and physiological functions.

01:03Basal Lamina are the Specialized Form of ECM
The basal lamina is a thin extracellular layer that lies underneath the cells and separates them from other tissues. The three layers of the basal lamina are lamina lucida, lamina densa and lamina reticularis. The basal lamina, a mixture of glycoproteins and collagen, provides an attachment site for the epithelium, separating it from underlying connective tissue. The framework of basal lamina has other essential proteins such as laminins mesh, perlecan, entactin, and type IV collagen.

00:55Laminins are the Adhesive Proteins of Basal Lamina
Laminins are heterotrimeric proteins with high molecular mass found in the extracellular matrix. Each laminin molecule is composed of three chains, viz. alpha, beta, and gamma, coded by five, four, and three paralogous genes, respectively. Laminins are categories based on the compositions of the three chains.
In humans, the five forms of alpha chains are LAMA 1, LAMA 2, LAMA 3, LAMA 4, and LAMA 5. The four forms of beta chains are LAMB 1, LAMB 2, LAMB 3, and LAMB 4. The three forms of gamma...

01:11Fibril-associated Collagen
Fibril-associated collagens are a type of collagens present in the extracellular matrix with interrupted triple helices or FACIT (Fibril-associated collagens interrupted triple-helices). FACIT help connect and attach the collagen fibrils with each other as well as with other proteins of the extracellular matrix.
For example, the type II collagen fibrils in cartilage have covalently bound type IX fibril-associated collagens at regular intervals. Other types of fibril-associated collagens are...

01:13Collagens are the Major Structural Proteins of ECM
Three main types of fibers are secreted by fibroblasts: collagen fibers, elastic fibers, and reticular fibers. Collagen fiber is made from fibrous protein subunits linked together to form a long, straight fiber. Collagen fibers, while flexible, have great tensile strength, resist stretching, and give ligaments and tendons their characteristic resilience and strength. These fibers hold connective tissues together, even during the body's movement.

01:21Matrix Proteoglycans and Glycoproteins
Proteoglycans are extensively glycosylated proteins, commonly found in the extracellular matrix, interwoven with collagen fibers. Hyaline cartilage, the most common type of cartilage in the body, consists of short and dispersed collagen fibers associated with large amounts of proteoglycans. These proteoglycans have long negative charges that attract cations, which in turn attract water molecules. This influx of ions and water molecules swells up the proteoglycan like a water-soaked gel that can...
