Do not mess with it. If it's not in your app drawer it's a system application. deleting system files & apps is a great way to render a device unusable and useless. I can't count the number of posts I've read of people just deleting things because they didn't know what they were... and ended up with an expensive paperweight.
To answer your question, the operating system uses this application to install & uninstall other apps. I hope this helps.
