AKAPs act as scaffolding proteins co-ordinating phosphotase:kinase signaling at the cytoskeleton. They interact with PKAs and anchor them to specific sub-cellular compartments and participate in multiple cellular processes including growth, metabolism and differentiation. ASP, a 26KD protein, is a novel AKAP-interacting protein. It interacts with the amphipathic helix of AKAP3 and facilitates AKAP3-PKA interactions. It consists of a conserved N-terminal AKAP-binding domain and a central cysteine-rich Fz domain. It is specifically expressed in the sperms and might play a significant role in sperm motily and also facilitate cytoskeletal reorganization during spermiogenesis. Applications: Suitable for use in Immunohistochemistry. Other applications not tested. Recommended Dilution: Immunohistochemistry (Formalin fixed paraffin embedded): 1:50-1:100 Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
