IMPG2, Official Symbol IMPG2provided by HGNC Official Full Name interphotoreceptor matrix proteoglycan 2provided by HGNC Primary source HGNC:HGNC:18362 See related Ensembl:ENSG00000081148 MIM:607056; AllianceGenome:HGNC:18362 Gene type protein coding RefSeq status REVIEWED Organism Homo sapiens Lineage Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo Also known as RP56; VMD5; IPM200; SPACRCAN Summary The protein encoded by this gene binds chondroitin sulfate and hyaluronan and is a proteoglycan. The encoded protein plays a role in the organization of the interphotoreceptor matrix and may promote the growth and maintenance of the light-sensitive photoreceptor outer segment. Defects in this gene are a cause of retinitis pigmentosa type 56 and maculopathy, IMPG2-related.[provided by RefSeq, Mar 2011] Expression Low expression observed in reference dataset See more Orthologs mouse all
