The invention concerns CCRP-1 polynucleotides and polypeptides. The method may include initiating, by the first framework, a request to access the service provided by the second framework. The second housing can further pivot about a pivot point to a second position substantially orthogonal to the first position enabling access to both the top interface and to a rear interface of the mobile device. The user equipment accesses the CSG cell with the use of the CSG-ID.
