PROTEIN MONITORING THE ACTIVITY OF LOW-MOLECULAR WEIGHT GTP-BINDING PROTEIN

摘要

A protein monitoring the activity of a low-molecular weight GTP-binding protein which makes it possible to measure the activation of a non-invasive low-molecular weight GTP-binding protein; a gene encoding the above protein; an expression vector containing this gene; transformed cells and a transgenic animal expressing the above-described protein and carrying the above-described expression vector which is useful in measuring the activation of a non-invasive low-molecular weight GTP-binding protein; a method of measuring the activation of a low-molecular weight GTP-binding protein with the use of the above-described protein; and a method of screening a substance controlling the activity of a low-molecular weight GTP-binding protein.
