Nerve Tissue Proteins

Agrin - A protein component of the synaptic basal lamina. It has been shown to induce clustering of acetylcholine receptors on the surface of muscle fibers and other synaptic molecules in both synapse regeneration and development.

Synapsins - A family of synaptic vesicle-associated proteins involved in the short-term regulation of neurotransmitter release. Synapsin I (Protein I), the predominant member of this family, links synaptic vesicles to actin filaments in the presynaptic nerve terminal. These interactions are modulated by the reversible phosphorylation of synapsin I through various signal transduction pathways. The protein is also a substrate for cAMP- and calcium-calmodulin-dependent protein kinases. It is believed that these functional properties are also shared by synapsin II (Protein III).
