In this issue of Neuron, Kim et al. and Enomoto et al. show that DISC1 plays a key role in regulating postnatal brain development though interaction with Girdin. Girdin in turn regulates AKT signaling. Thus, another facet of the role of DISC1 is established, shedding more light on fundamental brain processes and the developmental basis of major psychiatric disorders.

In this study, using Jurkat cells, we show that DISC1 (disrupted in schizophrenia 1) and Girdin (girders of actin filament) are essential for typical actin accumulation at the immunological synapse. Furthermore, DISC1, Girdin and dynein are bound in a complex. Although this complex initially forms as a central patch at the synapse, it relocates to a peripheral ring corresponding to the peripheral supramolecular activation cluster (pSMAC). In the absence of DISC1, the classic actin ring does not form, cell spreading is blocked, and the dynein complex fails to relocate to the pSMAC. A similar effect is seen when Girdin is deleted. When cells are treated with inhibitors of actin polymerization, the dynein-NDE1 complex is lost from the synapse and the microtubule-organizing center fails to translocate, suggesting that actin and dynein might be linked. Upon stimulation of T cell receptors, DISC1 becomes associated with talin, which likely explains why the dynein complex colocalizes with the pSMAC. These results show that the DISC1-Girdin complex regulates actin accumulation, cell spreading and distribution of the dynein complex at the synapse.This article has an associated First Person interview with the first author of the paper.
