Description:	The formation and refinement of connections between neurons in the developing brain, and modulation of synaptic strength in the adult brain often rely on the stimulation of receptor tyrosine kinases by their ligands. Much can be learned about how this signaling works by using stable isotope labeling quantitative proteomic methods such as Stable Isotope Labeling by Amino Acids in Cell Culture (SILAC) and targeted protein isolation strategies. These sample preparation methods are then combined with liquid chromatography-Q-TOF or LTQ-Orbitrap tandem mass spectrometry to identify and compare the relative amounts of proteins in signal transduction complexes from stimulated and nonstimulated cells. I will describe the use of SILAC in our lab to study ephrin signaling in NG108 cell cultures and BDNF signaling in primary cortical neurons. I will also describe SILAC experiments to characterize activity-dependent changes in postsynaptic density composition in primary neuronal cell culture. http://proteome.nih.gov
