TLDR Coordinated gene activities are crucial for normal hair growth.
This review article summarized the genetic and biochemical aspects of keratin synthesis by hair follicles, highlighting the importance of coordinated gene activities for hair follicle matrix cell differentiation and normal hair growth. It was found that keratin genes are organized in clusters, typically 5-10 kb in size, within the genome. Two keratin intermediate filament (IF) gene families and five keratin-associated protein (KAP) gene families were identified, with some clusters mapped. The proximity of these clusters suggested that "global" regulatory domains might control their expression.
