Abstract
Galectin-1 (GAL1) is a pre-B cell receptor (pre-BCR) ligand that induces pre-BCR clustering and leads to efficient pre-B cell proliferation and differentiation in the bone marrow. To study pre-BCR–GAL1 interactions and its functional consequence on the early steps of the B cell development, we combine structural nuclear magnetic resonance (NMR) approaches and B cell biology techniques. NMR is applied to identify the residues involved in pre-BCR–GAL1 interactions by monitoring chemical shift perturbations when the complex is formed. This structural information is then used at the cellular level to target specifically the complex formation during GAL1-induced pre-BCR clustering and lattice formation, using immunofluorescence techniques. Moreover, an in vivo assay was set up to study the consequence of synapse formation on the early steps of B cell development.
