Enables polychlorinated biphenyl binding activity. Involved in several processes, including response to lipopolysaccharide; response to ozone; and response to silicon dioxide. Located in several cellular components, including nuclear envelope; rough endoplasmic reticulum; and secretory granule. Biomarker of acute kidney failure; asthma; otitis media; and pulmonary fibrosis. Human ortholog(s) of this gene implicated in IgA glomerulonephritis; asthma; and glomerulonephritis. Orthologous to human SCGB1A1 (secretoglobin family 1A member 1). [provided by Alliance of Genome Resources, Apr 2022]
