I screwed up-- the first person had it right. Here's their answer: "A protein is composed of several amino acids chained together - so no melanin is not a protein. Melanin is formed from the amino acid Tyrosine and is NOT a chain of amino acids thus it is not a protein nor is it a amino acid."
The eye color gene encodes for a protein called OCA2 (P gene), which helps determine the amount of melanin produced in the iris. Melanin is responsible for the color of the eyes, with more melanin resulting in darker eye color.
Some are passive (e.g. melanin) and some are active (e.g. actin, myosin).
The missing protein in people with albinism is called tyrosinase. Tyrosinase is an enzyme that plays a key role in the production of melanin, the pigment that gives color to the skin, hair, and eyes. Its absence or low activity in individuals with albinism leads to a lack of melanin production, resulting in their characteristic pale skin, hair, and eyes.
Melanin is the pigment found primarily in skin, giving it a brown colour whilst absorbing UV radiation and transforming it into harmless heat energy. It is also found in the hair, the tissue underlying the iris, and in some parts of the brain.dark hair, dark skin.
The protein associated with eye color is called OCA2 (Oculocutaneous Albinism II). The R group of certain amino acids within the OCA2 protein plays a crucial role in the production and distribution of melanin in the iris, which determines eye color. Variations in the OCA2 gene can lead to different eye colors by influencing the amount and type of melanin produced. Additionally, other genes, such as HERC2, also interact with OCA2 to further affect eye color.

The protein responsible for hair color is melanin. There are two types of melanin: pheomelanin and eumelanin. Pheomelanin produces yellow and red color. Eumelanin produces browns.

No, it is not true that melanin is the most abundant protein in dead epidermal structures like hair and nails. The primary protein present in these structures is keratin, which provides strength and resilience. Melanin, on the other hand, is a pigment responsible for color and is found in the living cells of the skin, hair, and eyes, but not in significant amounts in the dead structures themselves.

The answer: a
Melanocytes produce melanin.
