- Abstract
Cellular and plasma fibronectin dimers are constituted by similar but not identical polypeptides. Their differences are the consequence of internal primary sequence variability due to alternative splicing in at least 2 regions (ED and IIICS) of the pre mRNAs [1-8]. A detailed analysis of human liver fibronectin mRNA in these regions was carried out by isolating cDNA clones and determining their nucleotide sequence. A novel type of IIICS segment (coding for 64 amino acids) was present in the two cDNA clones studied and, as expected from previous S1 mapping studies [6], the ED segment was absent in both.
