The encoded protein is a proteoglycan that is thought to play a role in maintaining viability of photoreceptor cells and in adhesion of the neural retina to the retinal pigment epithelium. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Sep 2013]. * **UniProt Summary**: May interact with hyaluronan which may serve to form a basic macromolecular scaffold comprising the insoluble interphotoreceptor matrix. {ECO:0000269|PubMed:9813076}. |SEA| |extracellular matrix structural constituent| |visual perception| |sensory perception of light stimulus| |extracellular matrix| |sensory perception| |nervous system process| |system process| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp506|Momordin-Ic 10μM R08 exp506]]|-1.81| |[[:results:exp139|Nicotinamide Riboside 100μM R03 exp139]]|1.7| |[[:results:exp422|Wiskostatin 3μM R07 exp422]]|2.22| No correlation found to any other genes in chemogenomics.
