KRT83 (KRT82), KRTHB4 (KRT84), and KRTHB5 (KRT85). All hair keratins are expressed in the hair follicle; this hair keratin, as well as KRTHB1 and KRTHB6, is found primarily in the hair cortex. Mutations in the "KRT83" gene have been associated with monilethrix. KRT83 Keratin 83, also known as KRT83, is a protein which humans is encoded by the "KRT83" gene. The protein encoded by this gene is a member of the keratin gene family. As a type II hair keratin, it is a basic protein which heterodimerizes with type I keratins to form hair and nails. The type II hair keratins
Leg hair of the hormone testosterone in males that most females have a lower level of. Fibroblast growth factor 5 (FGF5) is a secreted signaling protein. The expression of this protein is detected in hair follicles from the mice that scientists have experimented on. The hair follicles are localized to the outer root sheath during one of the phases of the hair growth cycle. Such experiments conclude that the protein FGF5 functions as an inhibitor when pertaining to hair elongation. Seasonal changes are also known to affect hair growth. For instance, one experiment had concluded that the rate of hair growth for
