Properties of a New H+ Channel in the Cornea of the Eye

This image shows the single channel events recorded from an excised segment of Xenopus frog oocyte membrane using the patch-clamp technique which will be used in this project.

Be the first to characterize a newly discovered ion channel in the cornea of the eye.

Project description

The cornea of the eye is a transparent structure that allows the passage of light into the eye. The cornea contains a collagen matrix stroma whose transparency is partially determined by corneal endothelial cells which pump fluid out of the stroma. We are studying the role of SLC4A11, an endothelial cell membrane transporter, in this process. We hypothesize that the SLC4A11 protein is an H+ channel. A student investigator in this project will express SLC4A11 protein in Xenopus frog eggs and then use the excised-patch clamp technique to examine membrane patches from these oocytes for evidence of H+ channel events.

Project outcome

At the end of this project the student will design a poster that will present the project background, goals, data and conclusions. In addition, data acquired by the student may be used in a scientific journal article.
