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.

This study found that KRTAP2 proteins predominantly express in the hair shaft cortex of humans, interact with hair keratins, and play crucial roles in hair shaft keratinization.

This review examines genetic variation in the ovine KRTAP1.1 gene and its potential impact on wool quality, reporting no new findings but suggesting opportunities for developing gene markers for wool and pelt traits.

This study investigated the expression of KRTAP6 gene family in Gansu Alpine fine-wool sheep, finding significant expression during the anagen phase and a negative correlation between KRTAP6-1 and KRTAP6-5 expressions with wool fiber diameter and strength.

This study found that polymorphisms in KRTAP13.1, KRTAP27-1, and KRTAP24-1 were significantly associated with fiber diameter in Jiangnan cashmere goats, which may aid future breeding and conservation efforts.

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.

This study found that keratin-associated proteins related to metallothionein and occludin appear in various animals, suggesting they may have roles beyond hair characteristics and were later adapted for hair production.

This study identified polymorphisms in HGT-KRTAP7-1 and KRTAP8-1 genes in Argentine llamas that may impact fiber characteristics by altering amino acid residues critical for keratin-associated protein properties.

Glucocorticoid receptors help regulate genes important for skin health and hair growth.

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 study revealed that heterozygous mice with the hairy ear mutation exhibited significant gene expression changes related to hair growth, such as upregulation of hair keratin and keratin-associated proteins, shedding light on the Hoxc gene cluster's role in this phenotype.

This study found that oral collagen peptides increased the expression of genes related to epidermal and hair cycle development in hairless mouse skin.

This study found that oral collagen peptides increased expression of genes associated with epidermis development and the hair cycle in hairless mice, providing insights into their potential skin benefits.

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 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 the promoter region of the sheep KRTAP11-1 gene drives specific transcriptional activity in wool follicles, suggesting it may regulate hair keratinocyte specificity.

This study observed that the growth cycle of cashmere in Inner Mongolian cashmere goats consists of three phases, with genes KAP3–1, KRTAP 8–1, and KRTAP 24–1 closely correlating with this cycle.

In this study, a specific genetic variant of KRTAP6-2 in Longdong cashmere goats was associated with finer cashmere fiber diameter, suggesting its potential as a molecular marker for breeding improvements.

This study discovered that key genes like KAP3-1 and KRTAPs are closely linked to the growth cycle of cashmere in Inner Mongolian goats, identifying March as the primary cycle's onset.

In this study, the researchers identified key genes, including KAP and KRTAP, that correlate with the secondary hair follicle growth cycle in Inner Mongolian cashmere goats, emphasizing March as the significant transition month.

Gene expression in wool follicles changes with growth cycles, offering insights into wool and human hair growth.

This study found differential expression of genes related to hair fiber production in Pashmina and Barbari goats, potentially enhancing pashmina fiber quality and informing future enrichment analyses.

This study found that manipulating prolactin levels in New Zealand Wiltshire sheep induces wool follicle growth cycles, revealing gene expression changes that suggest roles for specific genes in follicle function.

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.

In this study, researchers found that the cashmere hair growth cycle is divided into three periods and key genes like KAP and KRTAP are positively correlated with these cycles in cashmere goats.

In this study, the researchers found that KAP3.1, KRTAP 8-1, and KRTAP 24-1 genes positively correlated with the growth cycle of cashmere in Inner Mongolia goats, aligning with the observed hair cycle phases.

This study identified nine novel KRTAP5 family genes associated with human hair formation, demonstrating preferential expression in hair roots and suggesting their role in hair development.

This paper discusses the role of the KRTAP gene family in the evolution of mammalian hair and its potential link to hair-related disorders, but reports no new research findings.

This study suggests that the CXCL8 gene may regulate cashmere fineness in Liaoning cashmere goats, providing new insights into the cellular mechanisms of cashmere growth and quality.

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.
