Predicted to enable actin monomer binding activity. Predicted to be involved in actin filament organization; collateral sprouting in absence of injury; and positive regulation of cell projection organization. Predicted to act upstream of or within several processes, including chordate embryonic development; liver development; and notochord development. Located in cell cortex and plasma membrane. Orthologous to human COBL (cordon-bleu WH2 repeat protein). [provided by Alliance of Genome Resources, Apr 2022]
