Opticin belongs to class III of the small leucine-rich repeat protein (SLRP) family. Members of this family are typically associated with the extracellular matrix. Opticin is present in significant quantities in the vitreous of the eye and also localizes to the cornea, iris, ciliary body, optic nerve, choroid, retina, and fetal liver. Opticin may noncovalently bind collagen fib... See more...

Entrez Gene Summary for OPTC Gene

  • Opticin belongs to class III of the small leucine-rich repeat protein (SLRP) family. Members of this family are typically associated with the extracellular matrix. Opticin is present in significant quantities in the vitreous of the eye and also localizes to the cornea, iris, ciliary body, optic nerve, choroid, retina, and fetal liver. Opticin may noncovalently bind collagen fibrils and regulate fibril morphology, spacing, and organization. The opticin gene is mapped to a region of chromosome 1 that is associated with the inherited eye diseases age-related macular degeneration (AMD) and posterior column ataxia with retinosa pigmentosa (AXPC1).

GeneCards Summary for OPTC Gene

OPTC (Opticin) is a Protein Coding gene. Diseases associated with OPTC include Open-Angle Glaucoma and Vitreous Syneresis. Among its related pathways are Degradation of the extracellular matrix. Gene Ontology (GO) annotations related to this gene include extracellular matrix structural constituent. An important paralog of this gene is LRWD1.

UniProtKB/Swiss-Prot Summary for OPTC Gene

  • Inhibits angiogenesis in the vitreous humor of the eye, and therefore represses neovascularization (By similarity). Binds collagen fibrils (By similarity). May be involved in collagen fiber organization via regulation of other members of the small leucine-rich repeat proteoglycan superfamily (By similarity).
