Activity summary

Cytokeratin 1 (CK1) also known as keratin 1 is a type II cytokeratin with a molecular mass of approximately 66 kilodaltons. Alongside Cytokeratin 2e (CK2e) these proteins form a part of the keratin family which are structural proteins in epithelial cells. Specifically CK1 and CK2e are expressed in the suprabasal cells of stratified epithelia like in the epidermis. These cytokeratins create filaments providing mechanical support and protecting epithelial cells from damage.

Biological function summary

Cytokeratins 1 and 2e contribute to the overall stability and rigidity of the epidermal layer. They participate in the assembly of the keratin intermediate filament complex which maintains the structural integrity of cells subjected to stress. As part of this filament network CK1 and CK2e interact with other cytokeratins such as CK10 forming a lattice structure essential for the skin barrier function. This interaction allows cells to withstand mechanical stress and abrasion important for maintaining skin health.

Pathways

CK1 and CK2e have roles in the regulation of cell proliferation and differentiation pathways. These proteins integrate into the epidermal differentiation complex influencing pathways like the Notch signaling pathway. The interaction with Notch signaling components helps regulate epidermal homeostasis by controlling the balance between proliferation and differentiation. CK1 and CK2e work alongside CK10 and other keratins promoting orderly differentiation and limiting excessive cell division.

Associated diseases and disorders

CK1 and CK2e relate significantly to skin disorders particularly ichthyosis and epidermolytic hyperkeratosis. Mutations or dysregulation of these cytokeratins can disrupt the structural integrity of skin cells leading to hyperproliferative disorders. Cytokeratin 1 displays connections to proteins involved in skin barrier maintenance such as filaggrin with disruptions in these associations contributing to disease phenotypes. Understanding these interactions aids in uncovering the pathological mechanisms driving these skin disorders.
