How many keratins are in the hair forming compartment?
Schematic presentation of mRNA expression patterns of human type I and type II hair keratins in the hair-forming compartment. (A) Zones of mRNA synthesis. In the hair cuticle, six keratins (four type I+two type II) are sequentially expressed, with K39 and K40 being the latest keratins in this compartment. The hair matrix/cortex region contains 11 keratins (seven type I+four type II) or 13 keratins (9 type I+4 type II) if the heterogeneous cortical expression of K38 and the expression of K37 in the central cortex of vellus hairs are included. The ratios indicate the number of type I and type II keratins at different levels of the hair-forming compartment. The hitherto-used keratin designations are given in parentheses. (B) Start of mRNA synthesis of human type I and II hair keratins. The onset of mRNA expression of individual hair keratins in various compartments of the follicle is indicated by their names. The size of the designations reflects the intensity of expression.
What is extracted keratin solution?
In the literature, solution extracts from hair are often called “extracted keratin solutions” or “extracted protein solutions.” However it should be noted that hair is made up of a number of components other than keratins and proteins. Human hair consists of 65–95 wt% proteins, 48,50 1–9 wt% lipids, 51 15–35 wt% water 52 and less than 1 wt% minerals and other trace components such as melanin, DNA, RNA and carbohydrates. Although the interest of this article is keratin, the non-keratin components in hair extracts can influence resulting material properties.
What are KAPs in hair?
KAPs are also an important component of hair proteins. At least 85 human KAP genes in five domains on four chromosomes have been identified. A systematic review of the human KAPs can be found here. 36c Based on their amino acid content, 68 of them are grouped as high sulfur KAPs (<30 mol% cysteine) or ultra-high sulfur KAPs (>30 mol% cysteine) and 17 of them fall into high glycine-tyrosine KAPs. The largest known KAP protein has a molecular weight of 53.9 kDa. However, the majority of KAPs have molecular weights between 10 and 20 kDa. 57 Natively, KAPs serve as natural cross-linkers of KIFs within the hair matrix. The combination of KIFs and KAP matrix play an important role in realizing hair’s mechanical properties. However, in the field of keratin-based biomaterials, the importance of KAPs has not been well studied.
Why are intermediate filament proteins important?
A prominent feature of intermediate filament proteins is their high degree of sequence diversity. Evolutionary pressure is apparently placed on the basic design of the rod domain but neither on its specific amino acid composition nor on the sequences in the highly variable end domains. This diversity enables intermediate filaments to perform isotype-specific functions in different cellular environments. It may explain why large intermediate filament multigene families have evolved and why the individual family members are still rapidly evolving. For example, silencing of a hair keratin gene in humans occurred as recently as 200 000–240 000 years ago ( Winter et al., 2001 ).
Where are keratins found in hair?
Specifically, we are interested in the keratins that are found in the hair shafts, which should be differentiated from those found within the hair follicles. Hair keratins have a higher content of the amino acid cysteine in their head and tail domains, compared with other keratins.
