This study found that genes encoding mouse high-glycine/tyrosine proteins show distinct spatial and temporal expression patterns in hair follicles, suggesting diverse protein distribution during hair growth cycles.

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 presents computational modeling and experimental analysis of the HGT protein KAP8.1, identifying key structural features that may influence hair's response to environmental conditions.

This study suggests that the mechanical robustness of hair may be enhanced by the binding interactions of keratin-associated proteins, particularly KAP8.1, with intermediate filament proteins.

This study identified a domain on human chromosome 21q22.1 containing various high glycine-tyrosine and high sulfur keratin-associated protein genes, revealing their diverse expression in hair-forming cells.

This study introduced a method to isolate and separate microfibrillar proteins from human hair, identifying previously undetected glycine- and tyrosine-rich proteins.

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.

This study found that while the KRTAP gene family is unique to mammals, humans have a similar number of these hair gene types as other primates despite having less body hair.

This article reviews extensive genetic polymorphisms in the keratin-associated proteins of human hair, indicating complexity but reporting no new clinical results and calls for further research on their potential impact on hair structure.

Keratin-associated proteins are crucial for hair strength and structure.

In this study, researchers found that the naked (N) gene in mice indirectly affects the synthesis of structural proteins in mouse hair, resulting in reduced high tyrosine protein content and unusual amino acid compositions.

This article reviews the composition and structure of mammalian hard keratins, focusing on the filamentous and nonfilamentous protein content, and reports no new experimental results.

This study suggests that some keratin-associated proteins with antecedents found in non-haired animals may have roles beyond hair characteristics, possibly contributing to the evolution of hair follicles.

In this study, experimentally induced weight loss in merino sheep led to a decrease in wool fiber diameter and increased expression of certain high sulfur and glycine-tyrosine proteins, potentially impacting wool quality and industry preferences.

Hair follicles have unique proteins that vary by species and are influenced by nutrition.

This study observed that hydrophobic modifications of hair matrix proteins significantly alter the humidity-dependent glass transition temperature of human hair.

This research explored methods to obtain transgenic sheep embryos expressing synthetic spider silk genes in hair follicles using somatic cell nuclear transfer, with successful in-vitro development observed.

This article reviews the classification and complexity of keratin protein groups in hair follicles, but reports no new experimental results on their transcriptional events.

This study found that Naked trait mice exhibit a decrease in certain low-molecular-weight proteins in their hair, which contain high levels of glycine and tyrosine, compared to normal mice.

This research found that variations in the KRTAP gene family are likely responsible for the diverse hair phenotypes seen among mammals, influenced by gene repertoire differences, expression, and evolutionary factors.

This study found that sheep possess a polymorphic KAP8-2 gene that shares high sequence identity with the KAP8-2 gene in goats and reindeer.

In this study, the identification of a novel KAP gene in sheep, named KRTAP36-1, was associated with increased prickle factor in wool, suggesting its potential as a genetic marker for breeding purposes.

This study found that hair from mice with the Naked trait mutation has significantly lower levels of glycine and tyrosine, suggesting a deficiency in a specific protein fraction.

This study identified two single-nucleotide polymorphisms and three haplotypes in the KRTAP7-1 gene across yak, taurine, and zebu cattle, with the BOVIN-KRTAP7-1*A haplotype most prevalent.

This study identified a novel keratin-associated protein, KAP24.1, which is specifically expressed in the human scalp and located in the hair cuticle.

This study reports that KRTAP-like proteins, which resemble keratin-associated proteins found in mammals, are also present in the cornified teeth of various lamprey species, suggesting these proteins may serve similar functions in skin appendages across different vertebrates despite independent evolutionary origins.

This study identified two evolutionarily conserved ultra-high-sulfur keratin proteins in human and sheep hair follicles, which are specifically expressed in the hair cuticle during the late stages of fiber development.

This study identified 16 novel high sulfur KAP genes and two KAP pseudogenes on chromosome 21q23, showing expression in a specific region of the hair fiber cuticle.

This study identified two high sulfur protein genes, B2E and B2F, in rats, which are expressed in hair cortical cells during anagen and contribute to hair fiber production.

This study identified a cluster of genes on chromosome 17 related to hair keratin-associated proteins, including 37 genes forming seven multigene families, localized in the hair shaft's upper cortex.
