SH3PXD2A (SH3 And PX Domains 2A, also known as TKS5): SH3PXD2A is a scaffold protein that plays a crucial role in the formation of podosomes and invadopodia—cellular structures involved in tissue remodeling, cell migration, and invasion. It is significant in cancer metastasis and angiogenesis by facilitating the breakdown of the extracellular matrix. SH3PXD2A’s function in cellular movement and interaction with the environment makes it a potential target for therapies designed to limit cancer spread.
