research In vivo formation steps of the hard α-keratin intermediate filament along a hair follicle: Evidence for structural polymorphism
Hair follicles form hard α-keratin filaments in four steps, showing structural differences.

5 / 1000+ resultsresearch Sequence analyses of Type I and Type II chains in human hair and epithelial keratin intermediate filaments: Promiscuous obligate heterodimers, Type II template for molecule formation and a rationale for heterodimer formation
Type I and Type II keratin chains can form heterodimers despite sequence differences.
research De novo filament formation by human hair keratins K85 and K35 follows a filament development pattern distinct from cytokeratin filament networks
In this study, transfection experiments showed that mutations in the K85 gene affect filament formation with K35, which may impact hair formation related to ectodermal dysplasia.
research Keratin formation in the hair follicle
This study examined developing hair cortex with electron microscopy and found that keratin fibrils form between specific regions in hair follicles and aggregate into twisted cables.
research A keratin scaffold regulates epidermal barrier formation, mitochondrial lipid composition, and activity
In this study, researchers found that the absence of type I or type II keratins in mice leads to severe skin barrier defects, highlighting keratins' crucial role in epidermal structure and function.
