Predicted to enable ATP binding activity and DNA binding activity. Predicted to be involved in several processes, including negative regulation of cell-cell adhesion mediated by integrin; negative regulation of peptidyl-serine dephosphorylation; and regulation of actin filament organization. Predicted to act upstream of or within isotype switching. Predicted to be located in actin cytoskeleton and plasma membrane. Predicted to be active in cytoplasm and nucleus. Orthologous to human SWAP70 (switching B cell complex subunit SWAP70). [provided by Alliance of Genome Resources, Apr 2022]
