"HMP-1 bound filamentous actin with an affinity in the single micromolar range even when complexed with the beta-catenin homolog HMP-2 or when present in a complex of HMP-2 and the cadherin homolog HMR-1 indicating that HMP-1 binding to F-actin is not allosterically regulated by the HMP-2.HMR-1 complex."xsd:string
