Summary: Predicted to enable actin filament binding activity. Involved in several processes, including antennal morphogenesis; hemocyte migration; and plasma membrane bounded cell projection organization. Located in several cellular components, including actin cytoskeleton; neuron projection; and neuronal cell body. Is expressed in several structures, including epithelial cell; epithelium; head epidermis primordium; mesoderm; and visceral mesoderm derivative. Human ortholog(s) of this gene implicated in retinitis pigmentosa and retinitis pigmentosa 30. Orthologous to human FSCN1 (fascin actin-bundling protein 1) and FSCN2 (fascin actin-bundling protein 2, retinal). [provided by Alliance of Genome Resources, Dec 2024]
