Keratin contamination is a common problem in mass spectrometry proteomic analyses, particularly in bottom-up mass spectrometry. The purpose of this study was to determine the protein contaminants introduced during the proteomic analysis of tear fluid.Human tear fluid samples were collected using Sch...

The epidermal barrier protects the body against mechanical injury, infection and dehydration. The respective contribution of type I and type II keratins which form the major cytoskeleton in epidermal keratinocytes in barrier formation and stress protection is incompletely understood. Here, we reveal...

Nails protect the soft tissue of the tips of digits in humans. In birds and mammals the equivalent claws are used for purposes including capturing prey, digging, climbing, fighting and maintaining dexterity and balance. The molecular mechanism of nail (and claw) development is largely unknown, but w...

Keratins 5 and 14 are critical for cytoskeletal integrity, as shown by missense mutations in these genes, which cause the severe skin fragility disorder epidermolysis bullosa simplex (EBS). The complexity of the pathomechanisms in EBS is not fully understood and no effective management exists. In ad...
