Title	The proteome of human iris - Defining the proteome of human iris, ciliary body, retinal pigment epithelium, and choroid
Description	The iris is a fine structure that controls the amount of light that enters the eye. Iris diseases that result in visual disability and blindness include iritis, primary angle closure glaucoma, and pigment dispersion syndrome. A detailed investigation of the proteome of the normal human iris may provide a foundation for new investigations into the iris biology and pathophysiology. We conducted an in-depth proteomic analysis of five normal irides. Proteins were fractionated using SDS-PAGE. After in-gel digestion, peptides were analyzed using LC-MS/MS on an Orbitrap Elite mass spectrometer. We identified 3,000 non-redundant proteins in the human iris, including 26 unambiguous protein isoforms. The proteins identified in the iris included numerous proteins involved in smooth muscle motility, melanosome development, extracellular matrix, and selenoproteins involved in redox signaling. The MS proteome database of the human iris may serve as a valuable resource for future investigations of the eye in health and disease.
