Abstract
The domain structure of the insulin receptor was investigated in liver and brown adipose tissue of developing rabbits. The structure of the binding domain (alpha-subunit) was analysed after covalent labelling with a 125I photo-reactive insulin analogue. The structure of the tyrosine kinase domain (beta-subunit) and the transmission of the hormonal signal from the alpha-to the beta-subunit were analysed by stimulating with insulin the autophosphorylation of the beta-subunit. Finally, the immunoreactivity of the receptor in developing tissues was assessed with anti-receptor antibodies. The results show that a functional insulin receptor can be detected at the early stages of fetal development in both tissues and is conserved throughout ontogenesis to adulthood.Entities:
