There are 1100 sequences terminators in the E. coli genome

Intrinsic terminators include palindromic regions that form hairpins varying in length from 7 to 20 bp. The stem-loop structure includes a G-C–rich region and is followed by a run of 7U residues.

Constitutively active Ras proteins (RasD) 

Replacement of the normal glycine 12 with any other amino acid (except proline) blocks the functional binding of GAP proteins and in essence “locks” Ras in the active GTP-bound state.

MAP4, are phosphorylated by a cyclin-dependent kinase (CDK) that plays a major role in controlling the activities of proteins in the course of the cell cycle.
