The C-terminus of the gamma2 chain but not of the beta3 chain of laminin-332 is indirectly but indispensably necessary for integrin-mediated cell reactions
Using a recombinant mini-laminin-332, we showed that truncation of the three C-terminal amino acids of the gamma2 chain, but not of the C-terminal amino acid of the beta3 chain, completely abolished alpha3beta1 integrin binding and its cellular functions, such as attachment and spreading. However, a synthetic peptide mimicking the gamma2 chain C-terminus did not interfere with alpha3beta1 integrin
