Claim: ACTR2 is a protein (long chain of amino acids) in humans whose specific function of has not been determined and is located at the cell surface.
Evidence: Actin-related protein 2 is a protein that in humans is encoded by the ACTR2 gene. The specific function of ACTR2 has not yet been determined. This complex is located at the cell surface and is essential to cell shape and motility through lamellipodial actin assembly and protrusion. Proteins are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues.
