Fig 1 CaMKⅡα triggers the fusion of two immiscible PSD condensates.
Fig 2 CaMKⅡα regulates the interaction between SAPAP and PSD-95.
Fig 3 Phosphorylation on the GBR of GKAP is sufficient to achieve the fusion of two immiscible PSD condensates.
Fig 4 Phosphorylation of multiple GBRs enhances phase separation of PSD proteins.
