Pkp4 Gene Summary [Rat]
Predicted to enable cadherin binding activity. Predicted to be involved in several processes, including cell-cell junction assembly; positive regulation of GTPase activity; and positive regulation of cytokinesis. Predicted to be located in several cellular components, including cell-cell contact zone; postsynaptic density; and spindle. Predicted to be active in several cellular components, including adherens junction; nucleus; and plasma membrane. Orthologous to human PKP4 (plakophilin 4).

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 Pkp4 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
