Predicted to enable lipopolysaccharide binding activity. Acts upstream of or within extracellular matrix organization; negative regulation of transcription by RNA polymerase II; and negative regulation of transforming growth factor beta receptor signaling pathway. Located in extracellular space and interstitial matrix. Is expressed in several structures, including embryo endoderm; genitourinary system; gut; humerus; and musculature. Orthologous to human NEPNP (nephrocan, pseudogene). [provided by Alliance of Genome Resources, Apr 2022]
