Abstract: Hair follicles are the basis for the growth of hair fibers,and determine the properties of wool fibers.Keratin is one of the important components of hair follicles.In recent years,some progresses have been made in hair follicle growth and development and the mining of keratin genes.The article reviewed the discovery of keratin genes,which were already equivalent to human keratin genes,but there were differences in number and classification.This paper introduced the morphological structure of hair follicles,briefly described the gene expression and localization of hair follicles keratin gene and the keratin influencing the character of hair fibers.The important effect of proteomics technology in hair follicle on the growth and development of hair follicle and fiber character was analyzed,in order to provide a new research idea for the growth and development of sheep hair follicles and the molecular breeding of wool traits.

Key words: hair follicle; keratin; localization; fiber traits; proteomics technology
