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 innate immune response; modulation by host of viral process; and negative regulation of viral entry into host cell. 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, Apr 2022]
