Pkp1 Gene Summary [Rat]
Predicted to enable DNA binding activity; cadherin binding activity; and lamin binding activity. Predicted to be involved in several processes, including ameloblast differentiation; desmosome organization; and positive regulation of macromolecule biosynthetic process. Predicted to be located in desmosome; nucleus; and perinuclear region of cytoplasm. Predicted to be active in several cellular components, including adherens junction; cornified envelope; and nucleus. Human ortholog(s) of this gene implicated in ectodermal dysplasia. Orthologous to human PKP1 (plakophilin 1). [provided by Alliance of Genome Resources, Apr 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 Pkp1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
