Human hair keratin genes hHa2 and hHb1 are located on chromosomes 17 and 12.

Keratin heterodimers are preferred for their specific and structural advantages.

This research observed that sheep and rabbit KAP6 genes, expressed in hair follicle cells, have high sequence similarity and indicate conservation due to evolutionary selection pressures.

mHa2 and mHa3 keratins have different structures and roles in mouse hair and tongue tissues.

This study found that K33A was significantly upregulated in lustrous Magra wool follicles, while other keratin and KAP genes showed downregulation, impacting wool's physical properties like luster.

This study identified goat hair keratin gHaⅠ with strong expression in the cortex of hair follicles, showing high sequence homology to sheep keratin.

Scientists identified and cloned specific keratin proteins in mouse hair.

This study extracted water-soluble keratin particles from chicken feathers and verified their structural properties, observing no irritative potential on hen's eggs and positive physiological effects on human skin cells, suggesting their suitability for use on damaged or irritated skin.

In this study, researchers extracted soluble keratin proteins from chicken feathers and found they maintain structural integrity with potential uses for damaged skin, exhibiting no irritative effects in ex vivo settings on hen's eggs.

In this study, researchers identified a putative ovine KAP24-1 gene in sheep, revealing four unique DNA sequences with some similarity to KRTAP24-1 sequences from other species.

This study achieved successful cloning of the ovine keratin associated protein 6-1 gene, which may facilitate future research on transgenic animals and hair follicle gene regulation.

This study found that conserved DNA motifs and expression patterns in keratin genes suggest functional regulatory similarities in hair follicle differentiation across different mammalian species.

This study identified numerous size polymorphisms in the human ultrahigh sulfur KAP4 genes due to intragenic sequence variations, suggesting these polymorphisms may have arisen through deletions and duplications during evolution.

This study identified four keratin genes associated with hair follicle development that were expressed more highly in super fine wool Xinji sheep compared to fine wool sheep.

This study found that human hair keratin genes contain a few simple sequence repeats, with one repeat in the exon of KRT31 and additional repeats in introns, varying in length compared to their orthologues.

This review discusses recent advances in understanding the structural hierarchy of trichocyte keratins, including their heterodimeric structure and distinct conformations impacting hair growth, with no new experimental results reported.

This study identified a novel human type I hair keratin, hHa3-II, as an isoform of a previously described hHa3 keratin, with distinct sequence differences indicating separate gene encoding.

This study identified a new ovine KRTAP21-1 gene variant in sheep, with wool yield affected by the variant, suggesting its potential as a genetic marker for improving wool production.

This study mapped 65 intermediate filament genes in the human genome, highlighting that the majority of keratin-related sequences are inactive pseudogenes, notably for keratins 8 and 18.

This study identified a human sequence likely coding for a new ultra-high sulphur protein, which may aid in understanding hair differentiation and the molecular basis of human trichothiodystrophy.

This study identified genetic regions evolving at different rates in hairless mammals, suggesting that specific genomic changes may contribute to the evolution of hairlessness across various species.

This study developed a mathematical model indicating that the amino acid sequences of intermediate filament proteins, rather than flexibility differences, significantly impact assembly rates.

This study found that regulatory sequences crucial for inducing K6a expression in response to epidermal injury are located in specific upstream regions of the K6a gene in transgenic mice.

This study isolated and sequenced the complete gene rKAP4L1, which encodes a cysteine-rich hair keratin-associated protein in rabbit hair follicles.

This study found that a 671-base pair promoter sequence from the ultra-high-sulfur keratin gene is sufficient to direct tissue-specific and development-specific expression of a reporter gene during hair growth in transgenic mice.

In this study, researchers identified five unique sequences of the ovine KAP13-3 gene, with potential implications for wool traits due to observed amino acid changes.

This study found that the fungus Microsporum gypseum enzymatically degrades keratin in human hair, with the sequence of degradation reflecting the keratinization and cystine content of individual hair components in vitro.

This study analyzed the KRTAP7 gene in four Indian camel breeds and found that the gene sequences were identical across breeds, with no observed SNPs in coding or non-coding regions.

In this study, expressing human K16 in the epidermis of K14 null mice prevented early skin blistering but led to age-related anomalies, indicating K16 and K14 have distinct roles despite their sequence similarity.
