In the current paper we set out to characterize posttranslational modifications and the laminin isoforms formed by laminin alpha1 and alpha5 chains. Comparative pulse-chase experiments and deglycosylation studies in JAR cells established that the M(r) 360,000 laminin alpha1 chain is glycosylated into a mature M(r) 400,000 band while the M(r) 370,000 laminin alpha5 chain is glycosylated into a M(r) 390,000 form that upon secretion is further processed into a M(r) 380,000 form. Hence, despite the shorter peptide length of alpha1 chain in comparison with the alpha5 chain, secreted alpha1 assumes a larger size in SDS-PAGE due to a higher degree of N-linked glycosylation and due to the lack of proteolytic processing. Immunoprecipitations and Western blotting of JAR laminins identified laminin alpha1 and laminin alpha5 chains in laminin-1 and laminin-10. In placenta laminin alpha1 chain (M(r) 400,000) and laminin alpha5 chain (M(r) 380, 000/370,000 doublet) were found in laminin-1/-3 and laminin-10/-11. Immunohistochemically we could establish that the laminin alpha1 chain in placenta is deposited in the developing villous and trophoblast basement membrane, also found to contain laminin beta2 chains. Surprisingly, a fraction of the laminin alpha1 chain from JAR cells and placenta could not be precipitated by antibodies to laminin beta1-beta3 chains, possibly pointing to an unexpected complexity in the chain composition of alpha1-containing laminin isoforms."xsd:string |
