using antisera to synthetic peptides based on cdna sequences of chicken and human alpha-integrin subunits to analyze the integrin complement of avian and mammalian cells , we show that band 2 of the chicken integrin complex contains alpha-subunits related to both alpha 3- and alpha 5-subunits of human integrins . alpha 3 beta 1 and alpha 5 beta 1 have both previously been shown in human cells to be fibronectin receptors and alpha 3 beta 1 can also act as a receptor for laminin and collagen .
