Genes affected

TENM2 (HGNC:29943): (teneurin transmembrane protein 2) Enables cell adhesion molecule binding activity and signaling receptor binding activity. Involved in several processes, including calcium-mediated signaling using intracellular calcium source; heterophilic cell-cell adhesion via plasma membrane cell adhesion molecules; and retrograde trans-synaptic signaling by trans-synaptic protein complex. Located in cell-cell junction and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]
