Hi Guys,

Can some one please tell me about what visinin does in the retina specifically chicken retina...I do know a little bit about that. But, if anyone could really give a good explanation about that, it would be really very helpful to me. Thanks in advance!

The visinin and visinin-like peptides represent a family of calcium-binding proteins that are highly expressed in the retina. Visinin has been shown to be a cone cell-specific protein with a molecular weight of 24 kD. Several members of the visinin family of genes have been isolated and characterized from different species. These peptides are believed to be involved in the processes of phototransduction.

And HERE is an article of research using visinin.
