Glossary Keratin Gene Expression

process where cells produce keratin proteins for hair and skin

Keratin gene expression refers to the process by which cells produce keratin, a type of protein that is a key structural component of hair, skin, and nails. This involves the activation of specific genes within a cell's DNA that encode for keratin proteins, leading to their synthesis and assembly. Understanding keratin gene expression is crucial for studying hair growth, skin disorders, and conditions like alopecia.
