FAM81A is a postsynaptic protein that regulates the condensation of postsynaptic proteins via liquid–liquid phase separation
Proteomic analyses of postsynaptic proteins have mostly overlooked those with poorly characterized functions, likely missing crucial contributors to synaptic biology. Through a meta-analysis the authors identify 97 postsynaptic proteins with poorly characterized function, and elucidate the role FAM81A, revealing that it regulates the condensation of postsynaptic proteins via liquid-liquid phase separation to affect the size and function of synapses.
