GIGYF1 (GRB10 Interacting GYF Protein 1): GIGYF1 is an adaptor protein that plays a key role in cellular signaling pathways, particularly those associated with the insulin and IGF-1 receptors. By interacting with the GRB10 protein, GIGYF1 helps regulate cell growth, differentiation, and metabolism. It is essential for maintaining insulin sensitivity and glucose balance, making it significant for metabolic control and diabetes. Additionally, GIGYF1 is involved in regulating mRNA translation and stability, impacting gene expression at the post-transcriptional level.
