The product of this gene belongs to a small family of adaptor proteins that are known to interact with a number of receptor tyrosine kinases and signaling molecules. This gene encodes a growth factor receptor-binding protein that interacts with insulin receptors and insulin-like growth-factor receptors (e.g., IGF1R and IGF2R). Overexpression of some isoforms of the encoded protein inhibits tyrosine kinase activity and results in growth suppression. This gene is imprinted in a highly isoform- and tissue-specific manner. Alternatively spliced transcript variants encoding different isoforms have been identified.^[5]

Mice whose paternally inherited Grb10 gene is inactivated are more aggressive while those whose maternally inherited allele is inactivated exhibit foetal overgrowth and are significantly bigger than wild-type litter-mates.^[9]
