I recently succeeded in endogenous co-IP of some erythrocyte 
membrane/peripheral proteins. the protocols and recipes in paper below may 
provide you with beginning at least. as you know IP is trial and error with 
different buffers/ detergents/ etc. However, you mention that you want to 
purify?? this protein by IP? IMHO you may end up wasting a lot of time for 
unusable amount of protein.
