Types of Proteins

Hemoglobin:

a red protein responsible for transporting oxygen in the blood of vertebrates. It contains an iron atom bound to a heme group.

Skin

Keratin:

Insoluble, usually high-sulfur content and filament-forming proteins.

The bulk of epidermal appendages such as:

hair, nails, claws, turtle scutes, horns, whale baleen, beaks, and feathers.

These keratinous materials are formed by cells filled with keratin and are considered ‘dead tissues’.

Keratin structures are among the toughest biological materials, serving as a wide variety of interesting functions, e.g. scales to armor body, horns to combat aggressors, hagfish slime as defense against predators, nails and claws to increase prehension, hair and fur to protect against the environment

Keratin is in skin.

Keratin production related illness

Harlequin ichthyosis:

Mutations in the ABCA12 gene cause harlequin ichthyosis.

The ABCA12 gene provides instructions for making a protein that is essential for the normal development of skin cells.

This protein plays a major role in the transport of fats (lipids) in the outermost layer of skin (the epidermis).

This condition is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations.

The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.

Myelin:

A mixture of proteins and phospholipids forming a whitish insulating sheath around many nerve fibers, increasing the speed at which impulses are conducted.

Schwann cell:

Also called neurilemma cell, any of the cells in the peripheral nervous system that produce the myelin sheath around neuronal axons. Schwann cells are named after German physiologist Theodor Schwann, who discovered them in the 19th century.
