Gab2 is a member of the GRB2-associated binding protein (GAB) gene family. Gab 2 protein plays a crucial role in cellular signaling pathways, particularly in growth factor receptor activation. Gab 2 functions as an adapter protein that facilitates signal transmission from activated receptor tyrosine kinases to downstream signaling molecules, influencing cellular responses such as proliferation and differentiation. Gab 2 interacts with SH2 domain-containing proteins, including SHP2, which is essential for mediating cytokine-induced gene activation. Such interaction links extracellular signals to intracellular responses, making Gab 2 vital for regulating various biological processes. Gab 2′s ability to form complexes with other signaling proteins orchestrates complex signaling networks, critical for maintaining cellular homeostasis and responding to environmental cues.
