Abstract:
:Frog integumentary mucin B.1 (FIM-B.1) represents a polymorphic extracellular mosaic protein which contains tandemly arranged serine/threonine-rich modules as well as cysteine-rich domains. The latter are probably important for oligomerization of FIM-B.1 and have also been found in many proteins of the complement cascade as well as regions homologous to von Willebrand factor. The repetitive modules are targets for extensive O-glycosylation. Previous cDNA cloning experiments clearly established polydispersities within the same individual, which originate from deletions/insertions in the repetitive domain. Here, we analyse part of the corresponding genomic region. Each repetitive unit as well as the cysteine-rich domain is encoded by an individual class 1-1 exon typical of shuffled modules. Alternative splicing of these multiple cassettes creates the polydisperse FIM-B.1 transcripts.
