SH3PXD2A (SH3 And PX Domains 2A, also known as TKS5): SH3PXD2A is a scaffold protein that plays a key role in the formation of podosomes and invadopodia — cellular structures involved in tissue remodeling, cell migration, and invasion. It is important in cancer metastasis and angiogenesis by aiding the breakdown of the extracellular matrix. SH3PXD2A’s role in cellular movement and environmental interaction makes it a potential target for therapies aimed at limiting cancer spread.
