Abstract:
| The alpha3Abeta1 integrin is a laminin receptor with a broad specificity for different laminin isoforms. Furthermore, it regulates the function of other integrins, like alpha2beta1, alpha5beta1 and alpha6Abeta1. In a yeast two hybrid screen of a human placenta cDNA library, we identified cDNAs coding for four different proteins that strongly interact with the conserved region of the cytoplasmic domain of the alpha3A integrin subunit. In addition to the cDNA for nucleotide exchange factor Mss4 and the putative tumour suppressor protein BIN1, two novel cDNAs were identified. Association analysis with different integrin subunits revealed them as cDNAs that encode binding proteins which react with a broad spectrum of alpha subunits. The conserved membrane proximal region of the alpha3A chain was identified as the binding site for all four proteins. They, therefore, may be involved in the regulation of general functions of integrins. |
