Anti-WASP family, member 1 antibodies are used for the immunodetection of the protein encoded by the WASF1 gene. In humans, the canonical protein has a reported length of 559 amino acid residues and a mass of 61.7 kDa. Its subcellular localization is in the cytoplasm. It is reported to be highly expressed in the brain. A member of the SCAR/WAVE protein family, it is known to be involved with cytoskeleton organization and the assembly of protein complexes. Post-translational modifications have been described, including phosphorylation. The gene encoding this protein is implicated in Neurodevelopmental disorder with absent language and variable seizures. Other names for this target antigen include SCAR1, WAVE, WAVE1, actin-binding protein WASF1, WAS protein family member 1, and NEDALVS. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
