Myocilin is a variably glycosylated 65kD secreted polypeptide. Myocilin is a member of Olfactomedin-related protein family. Myocilin is expressed in large amounts in various types of muscle, ciliary body, papillary sphincter, skeletal muscle, heart and other tissues. Myocilin is predominantly expressed in the retina. In normal eyes, it is found in the inner uveal meshwork region and the anterior portion of the meshwork. In contrast, in many glaucomatous eyes, it is found in more regions of the meshwork and appeared more intensively than in normal eyes, regardless of the type or clinical severity of glaucoma. Myocilin may participate in the obstruction of fluid outflow in the trabecular meshwork.Alternative Names: Myocilin, Trabecular Meshwork-Induced Glucocorticoid Response Protein, MYOC, GLC1A, TIGR
