Eppk1 - epiplakin 1

Enables keratin filament binding activity. Involved in several processes, including intermediate filament bundle assembly; negative regulation of keratinocyte migration; and regulation of epithelial cell proliferation. Located in several cellular components, including apicolateral plasma membrane; basal part of cell; and cell-cell junction. Colocalizes with keratin filament. Is expressed in several structures, including alimentary system; liver and biliary system; respiratory system; sensory organ; and skin. Orthologous to human EPPK1 (epiplakin 1).
