Predicted to enable cytoskeletal protein binding activity and protein heterodimerization activity. Predicted to be a structural constituent of skin epidermis. Predicted to be involved in several processes, including keratinocyte differentiation; positive regulation of epidermis development; and protein heterotetramerization. Predicted to act upstream of or within cellular response to calcium ion; intermediate filament organization; and keratinocyte development. Predicted to be located in cornified envelope; cytoplasm; and keratin filament. Human ortholog(s) of this gene implicated in epidermolytic hyperkeratosis. Orthologous to human KRT10 (keratin 10).
