KRT31 KRT31 Keratin, type I cuticular Ha1 is a protein that in humans is encoded by the "KRT31" gene. The protein encoded by this gene is a member of the keratin gene family. As a type I hair keratin, it is an acidic protein which heterodimerizes with type II keratins to form hair and nails. The type I hair keratins are clustered in a region of chromosome 17q12-q21 and have the same direction of transcription. Model organisms have been used in the study of KRT31 function. A conditional knockout mouse line called "Krt31" was generated at the Wellcome Trust Sanger Institute.
Hair plexus lateral funiculus and terminates in the lateral cervical nucleus. The plexus acts as a receptor. Hair plexus A hair plexus or root hair plexus is a special group of nerve fiber endings and serves as a very sensitive mechanoreceptor for touch sensation. Each hair plexus forms a network around a hair follicle and is a receptor, which means it sends and receives nerve impulses to and from the brain when the hair moves. Endings of sensory nerve fibers which form a plexus around a hair follicle in hairy skin. They are mechanoreceptors conveying touch sensation. Specifically, crude touch and pressure
