Does my 401k Roth effect my Roth IRA?

I have a Roth IRA and I'm wanting to put the cap of $5,000 into it every year. At work I also have a 401k Roth and was wondering if my contributions to that will effect what I can put into my Roth IRA. For instance, if I put $2,000 in my 401k Roth does that mean I can only put $3,000 in my Roth IRA? Or since one is a Roth IRA and the other is a 401k they have seperate caps?
