Summary
Desmoplakin (DP) links cell structures to intermediate filaments. This review details the purification, biochemical characterization, and structural analysis of its key domains, DPNT and DPCT.
Area of Science:
- Cell biology
- Structural biology
- Biochemistry
Background:
- Desmoplakin (DP) is essential for desmosome structure and function.
- DP bridges the desmosomal cadherin complex and intermediate filaments.
- DP has distinct domains: amino-terminal (DPNT) and C-terminal (DPCT).
Purpose of the Study:
- To review the purification and biochemical characterization of DP domains.
- To present structural analysis of the DPNT plakin domain.
- To analyze the structure of DPCT plakin repeat domains.
Main Methods:
- Purification of desmoplakin domains.

01:09Cytoskeletal Linker Proteins - Plakins
3.0K
Plakins are large proteins with binding domains for microtubules, microfilaments, intermediate filaments, and membrane-associated protein complexes at cell junctions. Plakin functions are evolutionarily conserved and are primarily involved in organizing the different components of the cytoskeleton by crosslinking them to each other and connecting them to the cell-matrix and cell adhesion complexes. They are also known to interact with signal transducers, serve as scaffolds for signaling...

01:05Desmosomes
9.1K
The term desmosome derives from the Greek words "desmo" and "soma" meaning "adhesion bodies." This structure was first observed during the late 1800s and described as small, dense nodules in the epidermis. Desmosomes are button-like structures that help form an interlinked network of intermediate filaments across the cells. These junctions are essential to hold cells together under mechanical stress and to maintain tissue integrity. Desmosomes are multi-protein...

01:18Detergent Purification of Membrane Proteins
6.8K
Detergents are used to purify the integral proteins of the membrane. The hydrophobic portion of the detergent can replace membrane phospholipids while solubilizing the membrane proteins. When detergent monomers reach a specific concentration in a solution called critical micelle concentration (CMC), they form micelles. Above CMC, the concentration of the detergent monomers remains in equilibrium with the micelle. The number of detergent monomers present in the CMC varies for each detergent, and...

01:35Disassembly of Intermediate Filaments
2.8K
Intermediate filaments (IFs) do not undergo spontaneous disassembly. Enzymes, kinases, and phosphatases add and remove phosphates from specific sites to regulate their disassembly. The IF concentration in the cytoplasm also regulates the disassembly. If the concentration crosses a threshold, it activates the protein kinases in the vicinity, allowing the phosphorylation of IFs.

01:39Mechanism of Filopodia Formation
3.4K
Filopodia are thin, actin-rich cellular protrusions that play an important role in many fundamental cellular functions. They vary in their occurrence, length, and positioning in different cell types, suggesting their diverse roles.
Their main function is to guide migrating cells during normal tissue morphogenesis or cancer metastasis by recognizing and making initial contacts with the extracellular matrix. However, they can also act as stationary cell anchors or help to establish communication...
