NCIt definition : A fusion protein encoded by the MSN/ALK fusion gene. This protein is comprised of
most of the moesin protein, including the band 4.1 region, fused to the cytoplasmic
domain of the ALK tyrosine kinase receptor protein, including the tyrosine kinase
domain.;
NCIt note : The MSN/ALK fusion protein is hypothesized to be a constitutively dimerized and activated
tyrosine kinase. MSN/ALK is localized at the plasma membrane.;
