The importance of the IGF-1 receptor in development is especially supported by the seminal experiments of Efstratiadis and co-workers (DeChiara et al., 1990, and personal communicasaphenous-vein 发表于 2025-3-26 10:07:09
and the Reconfiguration of Civil Societych and Schlessinger, 1990). The structure of the insulin receptor, defined using recombinant DNA techniques, exhibits a high degree of overall similarity with the receptor for the structurally related insulin-like growth factor (IGF), IGF-I (for review, see Czech, 1989).

Similar to these growth factors, the receptors for insulin and IGF-1 share a high degree of structural and functional properties.. Both these receptors are classified as Type I receptors being composed of two a sSpongy-Bone 发表于 2025-3-26 18:23:07
and the Reconfiguration of Civil Societyt cell types. The receptors show considerable similarity in primary sequence within a common disulphide linked (αβ)2 subunit structure. The insulin receptor-related receptor (IRR), a third member of this receptor family for which a ligand has yet to be identified, apparently has a much more restrict
