Krt1 Gene Summary [Rat]
Predicted to enable carbohydrate binding activity and protein heterodimerization activity. Predicted to be a structural constituent of skin epidermis. Predicted to be involved in several processes, including complement activation, lectin pathway; keratinization; and protein heterotetramerization. Predicted to act upstream of or within establishment of skin barrier and negative regulation of inflammatory response. Predicted to be located in cytoplasm and membrane. Predicted to be active in cornified envelope and keratin filament. Human ortholog(s) of this gene implicated in KRT1-related nonepidermolytic palmoplantar keratoderma; epidermolytic hyperkeratosis; epidermolytic hyperkeratosis 1; epidermolytic palmoplantar keratoderma 2; and keratosis palmoplantaris striata 3. Orthologous to human KRT1 (keratin 1). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Krt1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
