GKAP/DLGAP1 Proteins and Enzymes

GKAP, also known as DAP1, DLGAP, and SAPAP1, is an approximately 45 kDa cytoplasmic membrane associated protein. GKAP is a component of a neuronal postsynaptic complex that also includes PSD-95 and SHANK. This complex links neurotransmitter channels with the cytoskeleton and can promote NMDA R channel opening. Alternate splice forms of human GKAP have N-terminal and/or C-terminal truncations of human GKAP and are differentially expressed during brain development.
