Ptx3 Gene Summary [Rat]
Predicted to enable several functions, including (1->3)-beta-D-glucan binding activity; complement component C1q complex binding activity; and virion binding activity. Predicted to be involved in host-mediated suppression of symbiont invasion; negative regulation by host of viral process; and negative regulation of glycoprotein metabolic process. Predicted to act upstream of or within several processes, including opsonization; ovarian cumulus expansion; and positive regulation of nitric oxide biosynthetic process. Predicted to be located in extracellular matrix. Predicted to be active in extracellular space. Human ortholog(s) of this gene implicated in cystic fibrosis and invasive aspergillosis. Orthologous to human PTX3 (pentraxin 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 rat Ptx3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
