GIGYF1 (GRB10 Interacting GYF Protein 1): GIGYF1 is an adaptor protein that plays a crucial role in cellular signalling pathways, particularly those associated with insulin and IGF-1 receptors. Through its interaction with the GRB10 protein, GIGYF1 helps regulate cell growth, differentiation, and metabolism. It is vital for maintaining insulin sensitivity and glucose homeostasis, making it significant in metabolic regulation and diabetes. Furthermore, GIGYF1 is involved in the control of mRNA translation and stability, thereby affecting gene expression at the post-transcriptional level.
