Grhl2 Gene Summary [Rat]
Predicted to enable several functions, including DNA binding activity; DNA-binding transcription activator activity, RNA polymerase II-specific; and identical protein binding activity. Predicted to be involved in several processes, including bicellular tight junction assembly; epithelial cell differentiation; and nervous system development. Predicted to act upstream of or within several processes, including embryonic morphogenesis; face development; and lung lobe morphogenesis. Predicted to be located in cell-cell junction and nucleoplasm. Predicted to be active in nucleus. Human ortholog(s) of this gene implicated in autosomal dominant nonsyndromic deafness 28 and posterior polymorphous corneal dystrophy 4. Orthologous to human GRHL2 (grainyhead like transcription factor 2). [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 Grhl2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
