FRMPD4（FERM and PDZ domain containing 4），癌症关联基因，基因ID：9758，该基因编码一个包含蛋白质的多结构域（WW，PDZ，FERM）通过与其它蛋白（如psd-95）的相互作用，发挥树突棘形态发生和密度的正调控作用，维持兴奋性突触传递。[由RefSeq提供，2010年1月]This gene encodes a multi-domain (WW， PDZ， FERM) containing protein. Through its interaction with other proteins (such as PSD-95)， it functions as a positive regulator of dendritic spine morphogenesis and density， and is required for the maintenance of excitatory synaptic transmission.
