Summary
Keratins from wool, feathers, and hair are chemically similar. Serological studies show species specificity in keratins depends on sulfhydryl group redox state.
Area of Science:
- Biochemistry
- Protein Chemistry
- Immunology
Background:
- Keratins are structural proteins found in hair, feathers, and wool.
- Understanding keratin structure and properties is crucial for various applications.
Purpose of the Study:
- To investigate the chemical relationship between kerateine and metakeratin.
- To determine the species specificity of keratins and its underlying molecular basis.
Main Methods:
- Preparation of kerateine and metakeratin from diverse biological sources (wool, chicken feathers, human hair).
- Chemical analysis to compare the composition of prepared compounds.
- Serological studies to assess species-specific antigenic properties.
Main Results:
- Chemical analyses confirmed close structural relationships between kerateine and metakeratin.
- Serological results demonstrated distinct species specificity for each keratin source.
- Observed specificity was directly linked to the redox state of sulfhydryl groups within the keratin molecules.
Conclusions:
- Kerateine and metakeratin share fundamental chemical characteristics.
- Keratin's species specificity is an intrinsic property influenced by protein structure.
- The redox state of sulfhydryl groups is a key determinant of keratin's immunological specificity.

01:24Cells of the Epidermis
The epidermis is made of four or five layers of epithelial cells, depending on its location in the body. From deep to superficial, these layers are the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum.
The cells in all these layers except the stratum basale are called keratinocytes, a type of cell that manufactures and stores the protein keratin. The keratinocytes in the stratum corneum are dead and regularly slough away, being replaced by cells from...

01:31Types of Intermediate Filaments
The intermediate filaments are an essential component of the cytoskeleton. Presently six types of intermediate filament have been identified. Type I and II are acidic and basic keratin proteins. Type III is of mesodermal origin and comprises four proteins: vimentin, desmin, glial fibrillary acidic protein (GFAP), and peripherin. Vimentin is commonly found in mesenchymal cells, desmin in muscle cells, GFAP in astrocytes, while peripherin is found in peripheral nervous system neurons (PNS). Type...
01:09Cytoskeletal Linker Proteins - Plakins
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...
01:16Accessory Structures of the Skin: Hair and Hair Follicles
Hair and hair follicles are integral components of the integumentary system. Hair is a filamentous structure composed mainly of a protein called keratin. It is found on the surface of the skin throughout the body, except for areas such as the palms of the hands and soles of the feet.
Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Hair strands originate at the epidermal penetration called the hair follicle. The hair shaft is the part...

01:25Selectins
Cell adhesion is an essential aspect of multicellularity. While stable cell interactions usually occur between cells of the same type, transient cell interactions occur between cells of different tissue types, such as between neutrophils and endothelial cells. Selectins are one class of cell adhesion molecules (CAMs) that bind carbohydrate ligands to form transient cell adhesion. They are rod-like proteins with a long extracellular part of variable length ending with the lectin domain, which...
01:56Structural Protein Function
Structural proteins are a category of proteins responsible for functions ranging from cell shape and movement to providing support to major structures such as bones, cartilage, hair, and muscles. This group includes proteins such as collagen, actin, myosin, and keratin.
Collagen, the most abundant protein in mammals, is found throughout the body. In connective tissue, such as skin, ligaments, and tendons, it provides tensile strength and elasticity. In bones and teeth, it mineralizes to form...
