TENM3 (Teneurin-3): TENM3 is a gene that encodes a transmembrane protein from the teneurin family, which functions as a multifunctional regulator in neural development and synaptic connectivity. This protein directs axonal pathfinding, dendritic growth, and synaptic organisation, playing a key role in forming and refining neural circuits. Beyond development, TENM3 also supports synaptic maintenance and plasticity in the adult nervous system, influencing processes such as synaptic pruning and neurotransmitter release. Dysregulation of TENM3 has been linked to neurological disorders including autism spectrum disorders and schizophrenia, emphasising its crucial role in brain function.
