Abstract:
:Laminins, the major basement membrane glycoproteins, are composed of three subunits. We identified a splice variant of the human laminin alpha4 subunit transcript containing 21 extra nucleotides. A heptapeptide sequence, MDCPTIS, was inserted close to the two cysteine residues possibly involved in the intersubunit disulfide bonds. Both the authentic alpha4 subunit (alpha4A) and the variant with the heptapeptide insertion (alpha4B) were readily secreted as laminin-8 trimers (alpha4Abeta1gamma1 or alpha4Bbeta1gamma1) upon cotransfection with expression vectors for the beta1 and gamma1 subunits. The purified recombinant laminin-8 containing the alpha4B subunit was more potent in promoting cell spreading than that containing alpha4A, raising the possibility that the alternative splicing of the alpha4 subunit transcript regulates the cell-adhesive activity of laminin-8. Since both alpha4A and alpha4B transcripts were detected by RT-PCR in several human cell lines, these two isoforms of laminin-8 with differing cell-adhesive activities are present in the basement membranes of human tissues.
