CTCF mutation at R567 causes developmental disorders via 3D genome rearrangement and abnormal neurodevelopment.

The three-dimensional genome structure organized by CTCF is required for development. Clinically identified mutations in CTCF have been linked to adverse developmental outcomes. Nevertheless, the underlying mechanism remains elusive.

Planar cell polarity protein Celsr2 maintains structural and functional integrity of adult cortical synapses.

A few developmental genes remain persistently expressed in the adult stage, whilst their potential functions in the mature brain remain underappreciated. Here, we report the unexpected importance of Celsr2, a core Planar cell polarity (PCP) component, in maintaining the structural and functional integrity of adult neocortex. Celsr2 is highly expressed during development and remains expressed in adult neocortex.

Celsr2 regulates NMDA receptors and dendritic homeostasis in dorsal CA1 to enable social memory.

Social recognition and memory are critical for survival. The hippocampus serves as a central neural substrate underlying the dynamic coding and transmission of social information. Yet the molecular mechanisms regulating social memory integrity in hippocampus remain unelucidated.
