PA1-046 detects synaptic Ras-GTPase activating protein (SynGAP) from mouse and rat tissues.
The PA1-046 has been successfully used in Western blot and immunocytochemistry procedures. By Western blot, this antibody detects an ~135 kDa protein representing SynGAP from mouse brain tissue homogenate. Immunocytochemical staining of SynGAP in rat hippocampal neurons with PA1-046 yields a pattern consistent with vesicular staining.
PA1-046 immunogen is residues 947-1167 of rat SynGAP.
Synaptic Ras-GTPase activating protein (SynGAP) is a PDZ-domain interacting protein expressed almost exclusively in the brain. SynGAP has been shown to be a major component of postsynaptic density and associates with post synaptic density 95 kDa (PSD-95), a synaptic scaffold protein, and synaptic N-methyl-D-aspartate (NMDA) receptors. SynGAP Ras-GTPase activity has also been shown to be inhibited by phosphorylation by CaM kinase II, another abundant protein located in the postsynaptic density. It has been proposed that SynGAP may function as a negative regulator of MAP Kinase activation in the absence of active NMDA receptors.
