This week’s articles show that vesicle fusion proteins are involved in long-term potentiation and highlight the structural properties that contribute to functional differences between angiotensin II receptors.
NEUROSCIENCE
Postsynaptic vesicle fusion for LTP
Wu et al. show that synaptotagmins are required postsynaptically for recruitment of AMPA receptors during NMDA receptor–dependent long-term potentiation.
BIOCHEMISTRY
Understanding an enigmatic receptor
Zhang et al. report structural features that contribute to the unusual signaling properties of the angiotensin II type 2 receptor (see also Tate).
