Event Abstract Back to Event Disrupted-in-schizophrenia 1 in the intracellular calcium homeostasis Sung-Jin Park1 and Sang Ki Park1* 1 Pohang University of Science and Technology, Department of Life Sciences, Korea, South DISC1 (Disrupted-in-schizophrenia 1) has emerged as a convincing susceptibility factor for the major mental illnesses including schizophrenia, recurrent major depression, and bipolar disorders, but its mechanistic links to the diseases are yet to be fully understood. The calcium plays essential roles in diverse and fundamental biological processes of a cell and an organism. This maximized functional variety of calcium is based on its fast effects and its spatially and temporally dynamic properties, which is heavily dependent on the calcium buffering function of organelles such as endoplasmic reticulum (ER) and mitochondria. We found that DISC1 deficiency caused abnormalities in calcium buffering function of ER and mitochondria. DISC1 deficiency caused an exaggerated oscillation pattern of mitochondrial calcium concentration. Also, DISC1 is recruited to inositol-1,4,5-trisphosphate receptor 1 (IP3R1). The abnormality in the transport of calcium between ER and mitochondria was also observed, which implies that functionalities of the mitochondria-associated ER membrane were also affected. These results collectively indicate that DISC1 is a key regulatory factor of intracellular calcium dynamics. Works on its mechanistic aspects are in progress and we believe that the results will provide novel insight into the molecular events associated with major mental disorders.
