Opticin pripada klasi III porodice mali leucinom bogati ponavljajući protein (SLRP). Članovi ove porodice su tipski povezani sa vanćelijskim matriksom . Opticin je prisutan u značajnim količinama u staklastom tijelu očiju , a također i u rožnjači , irisu , cilijarnom tijelu , očnom živcu , horiodei , mrežnjači i fetusnoj jetri . Opticin može nekovalentno vezati kolagenske fibrile i regulirati morfologiju razmak i organizaciju vlakana . Opticinski gen mapiran je u regiji hromosoma 1 koja je povezana s nasljednom bolešću oka starosnom degeneracijom makule (AMD) i ataksijom stražnjeg stupca s retinskom pigmentozom (AXPC1).[6]
