Descriptions

The scaffold protein SH3 and PX domain-containing protein 2B (SH3PXD2B, also known as Tks4) is a member of the p47phox-related organizer superfamily and plays a key role in cell motility by affecting the formation of podosomes and invadopodia. In addition, Tks4 is involved in the epidermal growth factor (EGF) signaling pathway, in which EGF induces the translocation of Tks4 from the cytoplasm to the plasma membrane. Tks4 contains an N-terminal region: a phosphoinositide-binding PX domain is followed by two SH3 domains (tandem SH3) and a proline-rich region (PRR). The PRR is followed by a third and a fourth SH3 domain connected by a long (~420 residues) unstructured region. In the autoinhibited state, the tandem SH3 domain of Tks4 binds the PRR and thus the third SH3 domain interacts with the PX domain. The association of the PX domain and the third SH3 domain contributes to the formation of the autoinhibited conformation, and the PRR following the second SH3 domain folds back and associates with the tandem SH3, yielding a compact conformation.
