Heg1 Gene Summary [Mouse]
Predicted to enable calcium ion binding activity. Acts upstream of or within several processes, including circulatory system development; endothelial cell morphogenesis; and lymph circulation. Located in cell-cell junction and external side of plasma membrane. Is expressed in several structures, including alimentary system; brain; cardiovascular system; genitourinary system; and hemolymphoid system. Orthologous to human HEG1 (heart development protein with EGF like domains 1). [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 Heg1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
