Teneurin-3 (Tenm3)

Involved in neural development by regulating the institution of appropriate connectivity within the nervous system (PubMed:17478416, PubMed:17803360, PubMed:23028443, PubMed:25406022, PubMed:22499796, PubMed:29414938). Acts in both pre- and postsynaptic neurons in the hippocampus to control the assembly of a precise topographic projection: required in both CA1 and subicular neurons for the precise targeting of proximal CA1 axons to distal subiculum, probably by promoting homophilic cell adhesion (PubMed:29414938).

Promotes homophilic adhesion at a splicing isoform-dependent manner: most isoforms (isoform-type A and type-B) can mediate homophilic interaction (PubMed:29414938). Promotes axon guidance (PubMed:23028443).
