Role of Matrix Metalloproteases in Degradation of ECM01:23

Role of Matrix Metalloproteases in Degradation of ECM

Matrix metalloproteases (MMPs) are enzymes involved in the hydrolysis of proteins and glycoproteins of the extracellular matrix. MMPs are essential for the migration and proliferation of cells through the dense matrix network, throughout embryonic development, and throughout morphogenesis. The first MMP activity discovered was a collagenase in a tadpole's tail undergoing metamorphosis. The active collagen deposition and modifications lead to the morphogenesis of tadpoles into the adult body.

Cancer Cell Migration through Invadopodia01:35

Cancer Cell Migration through Invadopodia

Invadosome is a broad category of cell surface structures with proteolytic activity that  degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However, invadopodia can...
Translocation of Proteins into the Mitochondria01:19

Translocation of Proteins into the Mitochondria

Mitochondrial precursors are translocated to the internal subcompartments via independent mechanisms involving distinct protein machineries called translocases.
Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...
The Extracellular Matrix01:29

The Extracellular Matrix

Overview
In order to maintain tissue organization, many animal cells are surrounded by structural molecules that make up the extracellular matrix (ECM). Together, the molecules in the ECM maintain the structural integrity of tissue as well as the remarkable specific properties of certain tissues.
Composition of the Extracellular Matrix
The extracellular matrix (ECM) is commonly composed of ground substance, a gel-like fluid, fibrous components, and many structurally and functionally diverse...

Area of Science:

  • Biochemistry
  • Cell Biology
  • Molecular Biology

Background:

  • ADAMs (a disintegrin and metalloproteinase) are a protein family with critical roles in cell adhesion, migration, proteolysis, and signaling.
  • While all ADAMs possess metalloproteinase domains, only 13 human genes encode functional proteases, highlighting the importance of protein-protein interactions for other family members.

Purpose of the Study:

  • To provide a comprehensive overview of the human ADAM protein family.
  • To discuss their structure, function, regulation, and involvement in various diseases.

Main Methods:

  • Review of existing literature on ADAM proteins.
  • Analysis of their roles in ectodomain shedding, signaling pathways (Notch, Eph/ephrin), and physiological processes.
  • Examination of their links to pathological conditions.

Main Results:

  • Functional ADAM metalloproteinases, like ADAM-17 (TACE) and ADAM-10, are crucial for ectodomain shedding of growth factors and receptors, and signaling pathways.
  • ADAMs are essential for processes including epithelial development, spermatogenesis, and neuronal guidance.
  • Dysregulation of ADAMs is implicated in diseases such as cancer, cardiovascular disease, asthma, and Alzheimer's disease.

Conclusions:

  • The ADAM family plays fundamental roles in development and homeostasis.
  • Understanding ADAM structure, function, and regulation is key to addressing associated diseases.
