What is GTPase and how is it related to G-proteins?

G proteins are a family of proteins that can bind guanine nucleotides, guanosine triphosphate (GTP) to guanosine diphosphate (GDP). They play a role in transmitting signals from the exterior to the interior of cells. GTPases are actually a superfamily of GTP-binding proteins and like the G proteins, play a role in the transmission of mitogenic signals.
