Psd3 Gene Summary [Mouse]
Enables guanyl-nucleotide exchange factor activity. Predicted to be involved in regulation of ARF protein signal transduction. Predicted to act upstream of or within ARF protein signal transduction. Located in ruffle membrane. Is active in glutamatergic synapse and postsynapse. Is expressed in several structures, including brain; eye; genitourinary system; hemolymphoid system gland; and liver. Orthologous to human PSD3 (pleckstrin and Sec7 domain containing 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 mouse Psd3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
