This study provides evidence supporting a regulatory relationship between the transcriptional regulator Hoxc13 and Krtap16 genes, which are crucial for proper hair growth in mice.

This study identified a genetic locus associated with coat type in domestic dogs, showing certain variants linked to single-coated breeds and suggesting potential regulatory roles.

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.

This study identified and sequenced a goat hair keratin cDNA that matches closely with its sheep counterpart, showing strong expression in hair follicle cortex.

This review explains the genetic diversity of sheep wool keratin-associated protein genes and explores how this variation might be leveraged for selective breeding to enhance wool fiber traits.

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 reported variable expression levels of TRα and CRABPII genes during the prenatal development of cashmere goats, contributing to an understanding of hair follicle formation in these animals.

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 Super Merino sheep have a higher wool follicle density, finer fleece, and distinct gene expression compared to Small Tail Han sheep, which may inform future breeding and genetic interventions.

This study found that genetic variants in the goat KRTAP22-2 gene are associated with the mean fiber diameter of cashmere in Longdong Cashmere goats, suggesting these variants could serve as molecular markers for improving cashmere traits.

This study analyzed the genetic variations of the KAP20-1 gene in Chinese Tan sheep lambs and found that the G variant was linked to an increased mean fibre curvature in their fine wool fibres, potentially influencing breeding strategies for this wool trait.

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.

The study found that exposing Arbas Cashmere goats to a short photoperiod significantly increased cashmere production by extending the anagen phase of hair follicles, with gene expression changes identified as contributing factors.

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

This study generated a gene-edited cashmere goat with improved cashmere yield and fiber length by integrating VEGF at the FGF5 site, offering insights into hair growth mechanisms.

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.

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.

In this study, researchers sequenced the KRT71 gene in 102 dromedary camels to find genetic polymorphisms linked to hair shape, identifying 17 variants but none that fully explained hair shape variations, suggesting other genes may also play a role.

This study analyzed inner root sheath-specific genes in Tan sheep during various growth stages, finding peak expression at birth. The pattern of genes KRT71, KRT72, and TCHH is consistent with wool crimp, potentially influencing wool morphology.

This study found that Wan strain Angora rabbits with high wool production exhibited higher hair follicle density and identified long noncoding RNAs that may regulate this trait.

This study found that Wan strain Angora rabbits with high wool production had higher hair follicle density and identified five long noncoding RNAs as potential regulators of this trait.

This study identified novel genetic variations in the KRTAP22-2 gene among eight sheep breeds but found no association between these genotypes and wool fibre traits, indicating possible species-specific differences compared to goats.

This study reports that variation in the ovine TCHH gene may influence wool fibre curvature, with specific gene variants affecting the mean fibre curvature in sheep.

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.

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.

In this study, researchers found that the keratin-associated protein 36-1 gene (KRTAP36-1) allele C is linked to variations in mean fibre curvature of fine wool in Chinese Tan lambs, suggesting its role in their distinctive curly coat.

This study found that KAP7.1 and KAP8.2 genes were significantly more expressed in secondary hair follicles than primary follicles, suggesting their role in regulating cashmere fiber diameter.

This study suggests that the KAP 7 gene may serve as a potential molecular marker for genetic selection to improve staple length and greasy fleece weight in Rambouillet sheep.
