Transferrin structure

[Wolfgang Schechinger]

Hi all, 

could anyone please point me to a resource that might elucidate the 
structure of (human sero-) transferrin (TF)? I spent half the night 
hunting through databases but I couldn't find anything relevant 
despite AA sequence and iron binding sites. especially, I'm 
interested in how and where TF interacts with its receptor and how 
iron content might influcence that behavior.

Thanks for your help.

Wolfgang
