Enables integrin binding activity and neurotrophin receptor activity. Involved in several processes, including male gonad development; neuron projection development; and positive regulation of peptidyl-tyrosine phosphorylation. Located in several cellular components, including axon; external side of plasma membrane; and neuronal cell body. Part of plasma membrane protein complex and receptor complex. Used to study Parkinsonism. Biomarker of Parkinsonism; brain ischemia; and sciatic neuropathy. Orthologous to human GFRA1 (GDNF family receptor alpha 1).
