Predicted to enable several functions, including non-membrane spanning protein tyrosine kinase activity; phosphotyrosine residue binding activity; and transmembrane transporter binding activity. Acts upstream of or within several processes, including cellular response to growth factor stimulus; cellular response to retinoic acid; and positive regulation of nitrogen compound metabolic process. Located in actin filament and plasma membrane. Is expressed in several structures, including central nervous system; early conceptus; pancreas; placenta; and vagal nerve trunk. Orthologous to human YES1 (YES proto-oncogene 1, Src family tyrosine kinase). [provided by Alliance of Genome Resources, Apr 2022]
