What is the official name of the KRT6B gene?
The official name of this gene is “keratin 6B, type II.”
KRT6B is the gene's official symbol. The KRT6B gene is also known by other names, listed below.

What is the normal function of the KRT6B gene?
The KRT6B gene provides instructions for making a protein called keratin 6b or K6b. Keratins are a group of tough, fibrous proteins that form the structural framework of certain cells, particularly cells that make up the skin, hair, and nails. Keratin 6b is produced in the nails, the hair follicles, and the skin on the palms of the hands and soles of the feet. It is also found in the skin's sebaceous glands, which produce an oily substance called sebum.
Keratin 6b partners with a similar protein, keratin 17, to form molecules called keratin intermediate filaments. These filaments assemble into dense networks that provide strength and resilience to the skin, nails, and other tissues. Networks of keratin filaments protect these tissues from being damaged by friction and other everyday physical stresses. Keratin 6b is also among several keratins involved in wound healing.
Does the KRT6B gene share characteristics with other genes?
The KRT6B gene belongs to a family of genes called KRT (keratins).
A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.
