Predicted to enable SH2 domain binding activity; SH3 domain binding activity; and identical protein binding activity. Predicted to be involved in protein transport and regulation of endocytosis. Predicted to act upstream of or within small GTPase mediated signal transduction. Predicted to be located in cytosol; endosome; and nuclear speck. Predicted to be active in cytoplasm and intracellular membrane-bounded organelle. Orthologous to human RUFY1 (RUN and FYVE domain containing 1). [provided by Alliance of Genome Resources, Apr 2022]
