In short, yes. An example:

I have 2 routers talking iBGP between my PoP and some 
exchange, and the router at the exchange talks eBGP to 
other routers connected at that exchange:

PoP Router<--iBGP-->Exchange Router<--eBGP-->Peers

Routes being originated from my PoP router get announced 
to my exchange router via iBGP, which in turn 
re-advertises said routes to the other peers via eBGP 
(filtering issues taken into consideration, of course).

Mark.
