What is meant by and allosteric protein? Why are G-protein linked receptors described as allosteric, while tyrosine kinase receptors are not?

Allosteric means that when a lignad binds to a site for example in a protein that have four subunits as emoglobine, it makes easier the binding of others ligands to the others sites of the protein, because it causes a structural modification of other sites.... I hope I'm not wrong and that you can understand my explanation..
