Summary: Predicted to enable ATPase binding activity and actin binding activity. Predicted to be a structural constituent of cytoskeleton. Predicted to contribute to actin filament binding activity. Acts upstream of or within several processes, including cellular response to interferon-gamma; meiotic chromosome movement towards spindle pole; and meiotic cytokinesis. Located in brush border; cell-cell junction; and lamellipodium. Is expressed in several structures, including alimentary system; blastocyst; genitourinary system; hemolymphoid system gland; and liver. Human ortholog(s) of this gene implicated in opisthorchiasis. Orthologous to human ACTR3 (actin related protein 3). [provided by Alliance of Genome Resources, Apr 2022]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
