    • The present invention provides methods and compositions for modulating the phosphorylation of DARPP-32 in a serotonergic receptor intracellular signaling pathway. The invention provides methods and compositions for modulating the activities of DARPP-32, casein kinase 1 (CK1), cyclin-dependent kinase 5 (Cdk5), AMPA receptors, protein phosphatase-1 (PP-1), protein phosphatase 2C (PP2C), protein phosphatase 2B (PP2B) and/or protein phosphatase 2A (PP2A) in cells or tissues. The invention provides methods of treating serotonergic intracellular signaling pathway disorders, e.g., depression. The invention provides methods of treating dopamine-related disorders. The invention provides methods of identifying agents that modulate the activities of serotonergic receptor intracellular signaling molecules, DARPP-32, casein kinase 1, cyclin-dependent kinase 5, AMPA receptors, protein phosphatase-1, protein phosphatase 2C, protein phosphatase 2B and/or protein phosphatase 2A, for use in such treatments. The invention also provides methods of modulating phosphorylation-dependent activation of AMPA receptors for use in such treatments.

    • A new synapsin protein, designated synapsin III, its amino acid sequence, and its human gene have been isolated and characterized. Furthermore, isoforms of synapsin III, e.g., synapsin IIIa, IIIb and IIIc, and have isolated and characterized, and cDNA encoding these isoforms has also been isolated and characterized. The synapsin III gene is located on human chromosome 22, in the vicinity of a region previously identified as a susceptibility locus for schizophrenia. The information and experimental tools provided by this discovery can be used to generate new therapeutic agents or diagnostic assays for this new protein, its associated mRNA or its associated genomic DNA. Due to its role in neurotransmission and synaptogenesis, isoforms of synapsin III are associated with the symptoms of psychiatric diseases, especially schizophrenia.
    • 已经分离并表征了新的突触蛋白,命名为突触蛋白III,其氨基酸序列及其人基因。 此外,已经分离并表征了突触蛋白III的同种型,例如突触蛋白IIIa,IIIb和IIIc,并且已经分离和表征,以及编码这些同种型的cDNA。 突触素III基因位于人类染色体22上,在先前鉴定为精神分裂症易感基因座的区域附近。 该发现提供的信息和实验工具可用于为该新蛋白,其相关mRNA或其相关基因组DNA产生新的治疗剂或诊断测定。 由于其在神经传递和突触发生中的作用,突触素III的同种型与精神疾病,特别是精神分裂症的症状有关。
