Enables several functions, including cadherin binding activity; enzyme binding activity; and gamma-catenin binding activity. Predicted to be involved in several processes, including cell surface receptor signaling pathway; regulation of cell migration; and regulation of mast cell activation involved in immune response. Predicted to act upstream of or within protein autophosphorylation and signal transduction. Predicted to be located in cytosol and nucleus. Predicted to be extrinsic component of cytoplasmic side of plasma membrane. Predicted to colocalize with several cellular components, including chromatin; cytoskeleton; and lamellipodium. Orthologous to human FER (FER tyrosine kinase). [provided by Alliance of Genome Resources, Apr 2022]
