Disks large-associated protein 4 (DAP-4) also known as SAP90/PSD-95-associated protein 4 (SAPAP-4) is a protein that in humans is encoded by the DLGAP4 gene. [5] [6]
DAP-4 is a membrane-associated guanylate kinase found at the postsynaptic density in neuronal cells. It is a signaling molecule that can interact with potassium channels and receptors, as well as other signaling molecules. DAP-4 can interact with PSD-95 through its guanylate kinase domain and may be involved in clustering PSD-95 in the postsynaptic density region. The encoded protein is one of at least four similar proteins that have been found. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [6]
PSD-95 also known as SAP-90 is a protein that in humans is encoded by the DLG4 gene.
Discs large homolog 1 (DLG1), also known as synapse-associated protein 97 or SAP97, is a scaffold protein that in humans is encoded by the SAP97 gene.
Disks large homolog 3 (DLG3) also known as neuroendocrine-DLG or synapse-associated protein 102 (SAP-102) is a protein that in humans is encoded by the DLG3 gene. DLG3 is a member of the membrane-associated guanylate kinase (MAGUK) superfamily of proteins.
Disks large homolog 2 (DLG2) also known as channel-associated protein of synapse-110 (chapsyn-110) or postsynaptic density protein 93 (PSD-93) is a protein that in humans is encoded by the DLG2 gene.
Glutamate [NMDA] receptor subunit epsilon-2, also known as N-methyl D-aspartate receptor subtype 2B, is a protein that in humans is encoded by the GRIN2B gene.
Glutamate [NMDA] receptor subunit epsilon-1 is a protein that in humans is encoded by the GRIN2A gene. The canonical GluN2A subunit isoform encompasses 1464 amino acids. Alternative splicing can generate a primate-specific GluN2A-short isoform.
Potassium voltage-gated channel subfamily A member 4 also known as Kv1.4 is a protein that in humans is encoded by the KCNA4 gene. It contributes to the cardiac transient outward potassium current (Ito1), the main contributing current to the repolarizing phase 1 of the cardiac action potential.
Kinesin-like protein KIF1B is a protein that in humans is encoded by the KIF1B gene.
Exocyst complex component 4 is a protein that in humans is encoded by the EXOC4 gene.
SH3 and multiple ankyrin repeat domains protein 2 is a protein that in humans is encoded by the SHANK2 gene. Two alternative splice variants, encoding distinct isoforms, are reported. Additional splice variants exist but their full-length nature has not been determined.
Synaptic Ras GTPase-activating protein 1, also known as synaptic Ras-GAP 1 or SYNGAP1, is a protein that in humans is encoded by the SYNGAP1 gene. SYNGAP1 is a ras GTPase-activating protein that is critical for the development of cognition and proper synapse function. Mutations in humans can cause intellectual disability, epilepsy, autism and sensory processing deficits.
Disks large-associated protein 1 (DAP-1), also known as guanylate kinase-associated protein (GKAP), is a protein that in humans is encoded by the DLGAP1 gene. DAP-1 is known to be highly enriched in synaptosomal preparations of the brain, and present in the post-synaptic density.
Disks large-associated protein 2 is a protein that in humans is encoded by the DLGAP2 gene.
Ras GTPase-activating protein 3 is an enzyme that in humans is encoded by the RASA3 gene.
GTP-binding protein GEM is a protein that in humans is encoded by the GEM gene.
Leucine rich repeat containing 7 also known as LRRC7, Densin-180, or LAP1 is a protein which in humans is encoded by the LRRC7 gene.
Ras GTPase-activating protein 4 is an enzyme that in humans is encoded by the RASA4 gene.
Connector enhancer of kinase suppressor of ras 2, also known as CNK homolog protein 2 (CNK2) or maguin, is an enzyme that in humans is encoded by the CNKSR2 gene.
Brain-enriched guanylate kinase-associated protein is an enzyme that in humans is encoded by the BEGAIN gene.
Mary Bernadette Kennedy is an American biochemist and neuroscientist. She is a member of the American Academy of Arts and Sciences, and is the Allen and Lenabelle Davis Professor of Biology at the California Institute of Technology, where she has been a member of the faculty since 1981. Her research focuses on the molecular mechanisms of synaptic plasticity, the process underlying formation of memory in the central nervous system. Her lab uses biochemical and molecular biological methods to study the protein machinery within a structure called the postsynaptic density. Kennedy has published over 100 papers with over 20,000 total citations.
