Function
Structural component of intermediate filaments in basal keratinocytes of stratified epithelia (PubMed:11408584). Together with its obligate type I partner KRT14, contributes to the formation of the keratin intermediate filament network that provides mechanical stability and resilience to the basal layer of the epidermis (PubMed:11408584). Regulates the recruitment of Langerhans cells to the epidermis, potentially by modulation of the abundance of macrophage chemotactic cytokines, macrophage inflammatory cytokines and CTNND1 localization in keratinocytes (PubMed:19267394)
