Predicted to enable cell adhesion molecule binding activity; protein heterodimerization activity; and protein homodimerization activity. Predicted to be involved in several processes, including heterophilic cell-cell adhesion via plasma membrane cell adhesion molecules; neurogenesis; and positive regulation of gastrulation. Predicted to act upstream of or within cardiac cell fate specification; cardiac muscle cell proliferation; and gastrulation with mouth forming second. Predicted to be located in cytoplasm; nucleus; and plasma membrane. Predicted to be integral component of plasma membrane. Predicted to be active in neuron projection. Human ortholog(s) of this gene implicated in essential tremor 5. Orthologous to human TENM4 (teneurin transmembrane protein 4). [provided by Alliance of Genome Resources, Apr 2022]
