Professor Daisuke Mori's research lab focuses on the molecular mechanisms underlying neurodevelopmental disorders and cellular dynamics during cell division. The lab investigates key regulatory proteins such as NDEL1 and ARHGAP10, exploring their roles in microtubule organization, neuronal migration, and schizophrenia pathogenesis through kinase signaling and genetic variation analyses. Using advanced techniques like surface plasmon resonance and genome-wide copy-number variation screening, the lab uncovers post-translational modifications and RNA-binding protein functions in disease contexts. Current research emphasizes the interplay between cell cycle regulation, cytoskeletal dynamics, and neurodevelopmental pathways.

NDEL1 is a binding partner of LIS1 that participates in the regulation of cytoplasmic dynein function and microtubule organization during mitotic cell division and neuronal migration. NDEL1 preferentially localizes to the centrosome and is a likely target for cell cycle-activated kinases, including CDK1. In particular, NDEL1 phosphorylation by CDK1 facilitates katanin p60 recruitment to the centrosome and triggers microtubule remodeling. Here, we show that Aurora-A phosphorylates NDEL1 at Ser251
Schizophrenia (SCZ) is known to be a heritable disorder; however, its multifactorial nature has significantly hampered attempts to establish its pathogenesis. Therefore, in this study, we performed genome-wide copy-number variation (CNV) analysis of 2940 patients with SCZ and 2402 control subjects and identified a statistically significant association between SCZ and exonic CNVs in the ARHGAP10 gene. ARHGAP10 encodes a member of the RhoGAP superfamily of proteins that is involved in small GTPase
CUG-binding protein 1 (CUG-BP1) is a member of the CUG-BP1 and ETR-3-like factors (CELF) family of RNA-binding proteins, and is involved in myotonic dystrophy type 1 (DM1). Several mRNA targets of CUG-BP1 have been identified, including the insulin receptor, muscle chloride channel, and cardiac troponin T. On the other hand, CUG-BP1 has only a weak affinity for CUG repeats. We conducted quantitative-binding assays to assess CUG-BP1 affinities for several repeat RNAs by surface plasmon resonance
