CC -!- TISSUE SPECIFICITY: Highly expressed in hair follicles from scalp.
CC Specifically expressed in the of the hair companion layer follicle, a
CC single layered band of flat and vertically oriented cells between the
CC cuboidal outer root sheath (ORS) cells and the inner root sheath (IRS)
CC that stretches from the lowermost bulb region to the isthmus of the
CC follicle. Also expressed in medullated hairs. In nails, it is almost
CC exclusively present in the nail bed (at protein level).
CC {ECO:0000269|PubMed:14675170, ECO:0000269|PubMed:15292489,
CC ECO:0000269|PubMed:18032949, ECO:0000269|PubMed:9856802}.
CC -!- POLYMORPHISM: The Thr-161 variant may increase risk to develop
CC pseudofolliculitis barbae (PFB) [MIM:612318]. PFB is a common hair
CC disorder characterized by a pustular foreign body inflammatory reaction
CC that is induced by ingrown hairs of the facial and submental (barbea)
CC regions after regular shaving. It occurs predominantly in black males,
CC while it is rather rare and usually far less severe in Caucasian males.
CC -!- DISEASE: Loose anagen hair syndrome (LAHS) [MIM:600628]: In LAHS,
CC anagen hairs are easily pulled from the scalp. The hair is relatively
CC sparse and does not grow long. Hair of fair color and hair shafts of
CC reduced caliber, and an early age of onset are features. Usually the
CC hairs are not fragile and there are no areas of breakage.
CC {ECO:0000269|PubMed:11939812}. Note=The disease may be caused by
CC variants affecting the gene represented in this entry.
CC -!- MISCELLANEOUS: May be used as a marker of hair differentiation.
CC -!- MISCELLANEOUS: There are two types of cytoskeletal and microfibrillar
CC keratin, I (acidic) and II (neutral to basic) (40-55 and 56-70 kDa,
CC respectively).
CC -!- SIMILARITY: Belongs to the intermediate filament family.
CC {ECO:0000255|PROSITE-ProRule:PRU01188}.
