Grhl1 Gene Summary [Rat]
Predicted to enable several functions, including DNA binding activity; DNA-binding transcription activator activity, RNA polymerase II-specific; and protein homodimerization activity. Predicted to be involved in epidermis development and positive regulation of transcription by RNA polymerase II. Predicted to act upstream of or within several processes, including desmosome organization; establishment of skin barrier; and regulation of keratinocyte differentiation. Predicted to be located in nucleoplasm. Predicted to be active in nucleus. Orthologous to human GRHL1 (grainyhead like transcription factor 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 Grhl1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
