C5ar1 Gene Summary [Mouse]
Enables complement component C5a receptor activity. Involved in several processes, including glial cell activation; positive regulation of vascular endothelial growth factor production; and regulation of granulocyte chemotaxis. Acts upstream of or within defense response to Gram-positive bacterium; neutrophil chemotaxis; and response to peptidoglycan. Predicted to be located in apical part of cell; basolateral plasma membrane; and cell surface. Predicted to be active in plasma membrane. Is expressed in several structures, including brain; liver; neural ectoderm; and sensory organ. Orthologous to human C5AR1 (complement C5a receptor 1).

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 C5ar1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
