Predicted to enable chemorepellent activity and fibroblast growth factor receptor binding activity. Predicted to be involved in basement membrane organization; cell adhesion involved in heart morphogenesis; and fibroblast growth factor receptor signaling pathway. Predicted to act upstream of or within axon guidance; positive regulation of synapse assembly; and regulation of neuron migration. Predicted to be located in cell-cell junction. Predicted to be integral component of plasma membrane. Predicted to be active in extracellular space. Predicted to colocalize with focal adhesion. Orthologous to human FLRT2 (fibronectin leucine rich transmembrane protein 2). [provided by Alliance of Genome Resources, Apr 2022]
