RAS protein is a small G protein linked to multiple G protein-coupled receptor (GPCR) signaling cascades and is responsible for various types of cancer, but to this day, Ras is considered "undruggable." Multiple alternative regulators of G protein signaling (RGS) pathways have become the focus of ongoing efforts to identify new cancer therapeutics. We analyzed human cancer genome datasets and describe p60TRP, a recently identified GPCR-associated sorting protein (GPRASP), and its role in various types of cancer. We found that some regions of p60TRP were more prone to specific mutations, with two hotspots for mutations at E15 and E171.
