We present a resolution of the quantum measurement problem in which wavefunction collapse is a physical process driven by gravitational self-energy. When a quantum system exists in a superposition of states with distinct mass distributions, the gravitational self-energy EG of the superposition determines a definite collapse timescale au = /EG. Using crystallographically determined atomic coordinates of tubulin proteins (PDB: 6EVW, 6EVZ), we compute EG for a biologically realized
