What's Happening?
A recent study published in Nature investigates the activation mechanism of the kainate receptor GluK2-Neto2 complex. Researchers used patch-clamp current recordings and cryo-electron microscopy to analyze the receptor's function and structure. The study found that the presence of BPAM344 significantly slows desensitization of the receptor, with desensitization becoming 270 times slower compared to when BPAM is absent. The research also explored the structural changes in the receptor, revealing that the GluK2-Neto2 complex undergoes specific conformational changes upon activation by kainate and BPAM. These findings provide insights into the receptor's kinetics and potential regulatory mechanisms.
