Enables protein tyrosine kinase activity. Predicted to be involved in several processes, including positive regulation of peptidyl-tyrosine phosphorylation; regulation of clathrin-dependent endocytosis; and spermatid development. Predicted to be located in several cellular components, including clathrin-coated pit; cytoophidium; and cytoplasmic vesicle. Predicted to be part of Grb2-EGFR complex. Predicted to be extrinsic component of cytoplasmic side of plasma membrane. Orthologous to human TNK2 (tyrosine kinase non receptor 2). [provided by Alliance of Genome Resources, Apr 2022]
