Predicted to enable fibroblast growth factor receptor binding activity. Predicted to be involved in dendrite development; fibroblast growth factor receptor signaling pathway; and neuron projection extension. Predicted to act upstream of or within positive regulation of synapse assembly. Predicted to be located in several cellular components, including neuron projection terminus; neuronal cell body membrane; and perinuclear region of cytoplasm. Predicted to be integral component of plasma membrane. Predicted to be active in extracellular space. Predicted to colocalize with focal adhesion. Orthologous to human FLRT1 (fibronectin leucine rich transmembrane protein 1). [provided by Alliance of Genome Resources, Apr 2022]
