Bipolar disorder (BD), characterized by recurrent mood swings between depression and mania, is a highly heritable and devastating mental illness with poorly defined pathophysiology. Recent genome-wide molecular genetic studies have identified several protein-coding genes and microRNAs (miRNAs) significantly associated with BD. Notably, some of the proteins(More)
Ca(2+) influx through Ca(2+)-release activated Ca(2+) channels (CRAC) is critical for activating immune cells. Orai and STIM proteins comprise the molecular components of CRAC. We previously observed that curcumin and caffeic acid phenethyl ester (CAPE) inhibit CRAC current in Orai1/STIM1-co-expressing HEK293 cells (Nam et al., 2009; Shin et al., 2011)(More)
Dysfunction of inhibitory GABAergic interneurons is considered a major pathophysiological feature of various neurodevelopmental and neuropsychiatric disorders. The variants of SHANK3 gene, encoding a core scaffold protein of the excitatory postsynapse, have been associated with numerous brain disorders. It has been suggested that abnormalities of GABAergic(More)
Actin dynamics is a critical mechanism underlying many cellular processes in neurons. The heteropentameric WAVE-regulatory complex (WRC), consisting of WAVE, CYFIP1/2, Nap, Abi, and HSPC300, is a key regulator of actin dynamics that activates the Arp2/3 complex to initiate actin polymerization and branching. The WRC is basally inactive because of(More)
Variants of the SHANK3 gene, which encodes a core scaffold protein of the postsynaptic density of excitatory synapses, have been causally associated with numerous brain disorders. Shank3 proteins directly bind zinc ions through their C-terminal sterile α motif domain, which enhances the multimerization and synaptic localization of Shank3, to regulate(More)
Mania causes symptoms of hyperactivity, impulsivity, elevated mood, reduced anxiety and decreased need for sleep, which suggests that the dysfunction of the striatum, a critical component of the brain motor and reward system, can be causally associated with mania. However, detailed molecular pathophysiology underlying the striatal dysfunction in mania(More)
Recent molecular genetic studies have identified 100s of risk genes for various neurodevelopmental and neuropsychiatric disorders. As the number of risk genes increases, it is becoming clear that different mutations of a single gene could cause different types of disorders. One of the best examples of such a gene is SHANK3, which encodes a core scaffold(More)
