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