Popis: cDNA clones representing a small (0.8 kb) form of murine mucosal addressin cell adhesion molecule-1 (MAdCAM-1) mRNA were obtained and sequenced. The sequence was identical to the published 1.6 kb murine MAdCAM-1 cDNA sequence, except that 432 nucleotides encoding the mucin-like and IgA-homologous portions were deleted. This cDNA most likely represents an alternately spliced mRNA. Substantial amounts of both the short and long MAdCAM-1 mRNAs are present in murine mesenteric lymph node. Ig fusion proteins displaying either the short or long forms of MAdCAM-1 can bind Mn ++ -activated JY cells bearing human α4β7 integrin, indicating that the two N-terminal Ig-like domains of MAdCAM-1 are sufficient to bind its integrin counter-receptor.
