DESCRIPTION (provided by applicant): Vesicle trafficking of neurotransmitters, neuronal response to nitric oxide, and SOCaE are critical functions in neurons. The InsP3-R may be a crucial regulator of these processes (see sec 30b). Binding partners of the InsP3-R that we identify may modulate such regulation. Recent work in this field has demonstrated that the InsP3-R is a central entity in many Ca2+ signaling pathways in neuronal systems. Identification of the microenvironment of proteins in which the InsP3-R resides will further our knowledge of InsP3-R, and its binding partners involvement within in neuronal signaling pathways. Additionally it will increase our knowledge of how the InsP3-R is able to discriminate between the many pathways that converge on its activity. The main objective of this proposal is to examine the role of the InsP3-R and InsP3-R signaling pathways in neurons. Specifically I intend to identify binding partners for the InsP3-R, and examine their roles in neurotransmitter secretion, SOCaE, and regulation of the InsP3-R itself.

描述（由申请人提供）： 神经递质的囊泡运输，神经元对一氧化氮的反应， 和SOCaE是神经元的关键功能。InsP 3-R可能是一个关键的 这些过程的调节器（见第30节b）。InsP 3-R的结合伴侣 我们发现可能会调节这种调节。最近在这一领域的工作 证明InsP 3-R是许多Ca 2+信号传导的中心实体 神经系统中的通路。微环境识别 InsP 3-R所在的蛋白质将进一步加深我们对InsP 3-R的了解， 以及其参与神经元信号传导途径的结合伴侣。 此外，它将增加我们对InsP 3-R如何能够 区分聚集在其活性上的许多途径。 该提案的主要目标是研究InsP 3-R的作用， InsP 3-R信号通路在神经元中的作用我特别想找出 InsP 3-R的结合伙伴，并检查它们在神经递质中的作用 分泌、SOCaE和InsP 3-R本身的调节。
