Pard3 Gene Summary [Rat]
Enables identical protein binding activity; phosphatidylinositol phosphate binding activity; and protein phosphatase binding activity. Involved in several processes, including bicellular tight junction assembly; establishment of epithelial cell polarity; and protein targeting to membrane. Located in axonal growth cone; cell-cell junction; and neuronal cell body. Part of protein-containing complex. Orthologous to human PARD3 (par-3 family cell polarity regulator).

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 Pard3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
