Pkp3 Gene Summary [Rat]
Predicted to enable alpha-catenin binding activity; cadherin binding activity; and enzyme binding activity. Predicted to be involved in several processes, including desmosome assembly; positive regulation of cell cycle G1/S phase transition; and regulation of gene expression. Predicted to be located in desmosome and nucleoplasm. Predicted to be active in several cellular components, including adherens junction; cornified envelope; and nucleus. Orthologous to human PKP3 (plakophilin 3). [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 Pkp3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
