Title	A proteomic map of human iris tissue
Description	The human iris tissue is a thin, circular structure in the eye and it is made up of a pigmented epithelial structure. It is a protected internal organ of the eye, located behind the cornea and the aqueous humour. Iris serves main function to control the diameter, size of the pupil and regulation of light exposure to the internal eye structures. Damage or absent iris always results in allowing excess amount of light into the eye which causes medical problem for the patient and also a psychological problem due to strange eye with black hole. A damaged or congenitally defective iris does not function well which results in poor quality of vision. Although different efforts have been made to elucidate the different parts of the human eye proteome in depth, the protein composition of the human iris tissue remains largely unexplored. We have performed a comprehensive analysis of the human iris tissue employing protein and peptide fractionation methods followed by LC-MS/MS identifying 4918 proteins. Bioinformatics analysis revealed that protein components of the iris tissue participated in a plethora of biological process highlighting cell signal transduction, communication, metabolism, energy pathways protein metabolism cell growth and maintenance, transport and immune response activities. We also compared the proteins of iris tissue with high throughput studies on other parts of eye and plasma proteome, which resulted in identifying proteins unique to iris. To our knowledge, this study is the first attempt to profile the global proteome of the human iris tissue. Taken together, these results increase our knowledge about the molecular composition of the human iris tissue and may be useful to understand the molecular basis of the iris and the baseline proteome described in this study should serve as a resource for future research in iris tissue
