Predicted to contribute to guanyl-nucleotide exchange factor activity. Predicted to be involved in positive regulation of epithelial cell migration and positive regulation of substrate adhesion-dependent cell spreading. Predicted to act upstream of or within cell migration and hematopoietic progenitor cell differentiation. Predicted to be located in cytosol and nuclear speck. Predicted to be part of guanyl-nucleotide exchange factor complex. Orthologous to human DOCK1 (dedicator of cytokinesis 1). [provided by Alliance of Genome Resources, Apr 2022]
