The disintegrin-like domain of ADAM23 promotes cell adhesion through a specific interaction with αvβ3 integrin via an RGD-independent mechanism; the short amino acid sequence in the disintegrin loop mediates this binding, and full-length ADAM23-transfected HeLa cells also support αvβ3-mediated adhesion. |

ADAM22 and ADAM23 modulate LGI1 trafficking: they promote LGI1 ER export and expression at the neuronal cell surface, and LGI1 is co-transported in axonal vesicles with ADAM22 and ADAM23 to the axon initial segment where it colocalizes with Kv1 channels. ADLTE missense mutations in LGI1 prevent its association with ADAM22 and enrichment at the AIS. |

ADAM23 is a negative regulator of Kv1.1 currents: ADAM23 expression causes decreased surface expression of Kv1.1 subunits and reduced voltage-gated potassium currents, independent of clathrin-mediated endocytosis. This effect is not reversed by LGI1-conditioned media, contrasting with ADAM22 which potentiates Kv1.1 currents in the presence of LGI1. |
