RHOQ and glioblastoma: PIST (PDZ domain protein interacting specifically with TC10), also called GOPC (Golgi-associated PDZ and coiled-coil motif-containing protein), CAL (CFTR-associated ligand) or FIG (fused in glioblastoma) was first described in 2001 as a coiled-coil and PDZ domain-containing protein that specifically interacts with the GTPase TC10 (Neudauer et al., 2001).
