Gene function

iDimerize Inducible Homodimer System

The iDimerize Inducible Homodimer System brings protein-protein interactions under real-time, small-molecule control. A protein of interest is fused to the DmrB binding domain, and dimerization is induced by adding the B/B Homodimerizer (identical to the AP20187 ligand). Plasmid and lentiviral (Lenti-X) vector formats are available.

NOTE: While it is possible to use the iDimerize Inducible Homodimer System to induce heterodimerization, you will obtain a mixture of homodimers and heterodimers. To induce heterodimers specifically and exclusively, use the iDimerize Inducible Heterodimer System.

iDimerize Inducible Homodimer Systems (with Tet-On 3G technology)

One challenge of ligand-dependent dimerization experiments is that non-ligand-induced dimerization events may occur if the protein of interest is expressed at high levels. This is especially problematic if the target protein is a membrane protein, because the local concentration can increase quickly due to the limited space on the membrane. We've combined iDimerize and Tet-On 3G technologies to eliminate these unwanted events. First, use doxycycline to optimize the protein's expression to physiologically relevant levels. Then induce dimerization by adding the dimerizer ligand to your culture medium.

The iDimerize Inducible Homodimer System lets you control the homodimerization of a protein of interest in live cells via a membrane permeant compound. The system includes the iDimerize Inducible Homodimer Vector Set 1, which contains two mammalian expression vectors encoding fusion tags that can be easily added to your protein of interest. The activity and localization of the resulting chimeric protein can be controlled by the addition of a small molecule to the cell medium. The system also includes the membrane-permeant compound, B/B Homodimerizer, required for homodimerization, and two linear selection markers for hygromycin and puromycin resistance.
