Cyth3 Gene Summary [Rat]
Predicted to enable guanyl-nucleotide exchange factor activity and phosphatidylinositol-3,4,5-trisphosphate binding activity. Predicted to be involved in Golgi vesicle transport. Predicted to act upstream of or within establishment of epithelial cell polarity and positive regulation of cell adhesion. Predicted to be located in several cellular components, including adherens junction; bicellular tight junction; and ruffle. Orthologous to human CYTH3 (cytohesin 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 rat Cyth3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
