Predicted to enable heparin binding activity and hyaluronic acid binding activity. Predicted to be involved in visual perception. Predicted to act upstream of or within extracellular matrix organization; protein localization; and retina morphogenesis in camera-type eye. Predicted to be located in interphotoreceptor matrix. Predicted to be part of receptor complex. Human ortholog(s) of this gene implicated in retinitis pigmentosa 56 and vitelliform macular dystrophy. Orthologous to human IMPG2 (interphotoreceptor matrix proteoglycan 2). [provided by Alliance of Genome Resources, Apr 2022]
