Enables (1->3)-beta-D-glucan binding activity. Acts upstream of or within several processes, including opsonization; ovarian cumulus expansion; and positive regulation of nitric oxide biosynthetic process. Located in extracellular matrix. Is expressed in cochlea; cochlea epithelium; inner ear vestibular component; organ of Corti; and stria vascularis. 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]
