Phylogenetic, sequence and structural analysis of Insulin superfamily proteins reveals an indelible link between evolution and structure-function relationship
Abstract:The insulin superfamily proteins (ISPs), in particular, insulin, IGFs and relaxins are key modulators of animal physiology. They are known to have evolved from the same ancestral gene and have diverged into proteins with varied sequences and distinct functions, but maintain a similar structural architecture stabilized by highly conserved disulphide bridges. A recent surge of sequence data and the structures of these proteins prompted a need for a comprehensive analysis which connects the evolution of these seq… Show more
