Gene: Impg2 (interphotoreceptor matrix proteoglycan 2) Rattus norvegicus
Symbol: Impg2
Name: interphotoreceptor matrix proteoglycan 2
CRRD ID: 708358
Description: Predicted to have heparin binding activity and hyaluronic acid binding activity. Predicted to be involved in visual perception. Predicted to localize to 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); INTERACTS WITH 2,3,7,8-tetrachlorodibenzodioxine; bisphenol A; flavonoids.
Type: protein-coding
RefSeq Status: VALIDATED
Also known as: Pg10.2; sialoprotein associated with cones and rods proteoglycan; spacrcan
