Overview
Receptor dimerization plays a critical role in cell signaling and has become a key target for cancer immunotherapy and immune modulation. By selectively inducing or inhibiting receptor dimerization, it's possible to fine-tune immune responses and alter cellular signaling pathways. Recent advances in antibody and fragment engineering have led to the creation of bispecific antibodies and small engineered fragments that can manipulate receptor pairing with high precision, offering enhanced selectivity, lower toxicity, and better efficacy. Creative Biolabs applies these cutting-edge techniques to engineer receptor dimerization tools that can improve therapeutic interventions.
Our approach to receptor dimerization engineering leverages the latest in protein design and functional screening:
-
Bispecific Antibody Engineering
We create bispecific antibodies that can bind to two different targets simultaneously, either inducing receptor dimerization or blocking unwanted interactions.
-
Fragmentation for Targeted Dimerization
Small fragments (e.g., Fabs, scFvs) are engineered to specifically bind receptor subunits and modulate dimerization, providing a cost-effective and flexible alternative to full antibodies.
-
Site-Specific Dimerization
Using hinge-region modifications or other engineering strategies, we guide the controlled pairing of receptor molecules, either enhancing or inhibiting receptor activity in a highly specific manner.
-
In Vivo Validation
Our engineered molecules undergo rigorous validation through functional assays and in vivo models to confirm dimerization and downstream effects on cell signaling pathways.
-
Modular Design
Our platform allows for easy adaptation of dimerization properties, enabling the creation of bispecifics, multispecifics, and even dimerized fragments for a variety of applications.
-
Customization
Depending on the therapeutic area, we can customize the dimerization approach to either enhance receptor activation (agonist) or block unwanted signaling (antagonist), catering to the specific needs of your project.

Binding of the growth factor FGF1 to the extracellular D2 and D3 domains of the receptor FGFR1 drives receptor dimerization, initiating the internalization process. In parallel, a bivalent antibody construct engaging the D1 domain of FGFR1 also induces dimer formation, bypassing ligand binding. Crucially, in both scenarios the dimerization of FGFR1 is sufficient to trigger uptake of the receptor into the cell, and this occurs even when the receptor's kinase activity is rendered inactive. Thus, the spatial juxtaposition of two FGFR1 monomers — whether via natural ligand or engineered antibody — acts as the key initiating event for endocytosis. By inducing FGFR1 dimer formation, the antibody mimics the effect of the ligand in promoting internalisation, highlighting dimerization rather than downstream kinase activation as the essential driver of receptor uptake.
