Pex3 Gene Summary [Mouse]
Predicted to enable lipid binding activity and protein-macromolecule adaptor activity. Predicted to be involved in peroxisome membrane biogenesis and protein import into peroxisome membrane. Predicted to be located in several cellular components, including endoplasmic reticulum; nucleoplasm; and peroxisome. Predicted to be part of protein-lipid complex. Predicted to be active in peroxisomal membrane. Is expressed in cerebral cortex ventricular layer; cortical plate; head; tail; and trunk. Human ortholog(s) of this gene implicated in Peroxisome biogenesis disorder 10B and peroxisome biogenesis disorder 10A. Orthologous to human PEX3 (peroxisomal biogenesis factor 3).

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 mouse Pex3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
