Novel cyclic AMP signalling avenues in learning and memory
... Interestingly, disruption of AKAP-PKA anchoring leads to CaN-dependent, long-term depression (LTD)-like down-regulation of AMPAR currents, implicating an important role for AKAP79/150 in AMPAR regulation (Tavalin et al., 2002). In general, the AKAP79/150 scaffold molecule has emerged as an important ...
