Impg2 - interphotoreceptor matrix proteoglycan 2

Enables heparin binding activity and hyaluronic acid binding activity. Acts upstream of or within extracellular matrix organization; protein localization; and retina morphogenesis in camera-type eye. Located in interphotoreceptor matrix. Is expressed in embryo; retina inner nuclear layer; retina nuclear layer; and retina outer nuclear layer. Used to study retinitis pigmentosa 56 and vitelliform macular dystrophy. 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]
