This study proposes a new method to selectively isolate keratin-associated proteins and keratin from human hair, suggesting that KAPs may support keratin fibers in hair structure.

This study identified two key pentapeptide quasi-repeats in human keratin-associated proteins, which are similar to motifs found in sheep wool.

In this study, researchers found that size polymorphisms in certain hKAP1 genes are linked to the hKAP1.1B and hKAP1.3 genes, arising from intragenic deletions and duplications in Japanese and Caucasian populations.

This study identified the distribution of keratin-associated proteins during cornification in the epidermis of reptiles, revealing unique structural characteristics in sauropsid keratin proteins compared to other vertebrates.

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.

In this study, two novel clusters of keratin-associated protein genes on human chromosome 11 were analyzed, suggesting their products are crucial for hair formation due to preferential expression in hair roots.

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.

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.

In this study, researchers identified two new keratin-associated proteins, hKAP1.6 and hKAP1.7, in human hair follicles, contributing to understanding hair fiber differentiation.

This study identified and characterized a gene called 4C32, which is expressed in the periderm of embryonic mouse skin and has a structure similar to keratin-associated proteins.

In this study, the presence of certain KAP15-1 gene variants in sheep was associated with differences in wool yield and fiber characteristics.

This study found that keratin-associated protein nanoparticles extracted from human hair significantly reduced clotting time, suggesting their potential as a hemostatic agent for bleeding control, though further research is needed to understand their precise role in coagulation processes.

In this study, oral collagen peptides increased certain gene expressions related to epidermis development and the hair cycle in hairless mice skin, suggesting potential links to hair health.

This review discusses the role of keratin-associated proteins in the growth and characteristics of wool and hair fibres from sheep and goats, and highlights areas for future research, but it presents no new findings.

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.

Hair proteins change location and structure as hair cells mature.

KAP genes are crucial for hair development and show both shared and unique traits in humans, chimpanzees, and baboons.

This study found that genetic variation in the KRTAP21-2 gene among crossbred Merino lambs was associated with differences in wool traits, particularly mean staple length.
