The function of the pre-B cell receptor (pre-BCR) during B cell differentiation is not precisely defined. To investigate the pre-BCR receptor activity, we have established pre-BCR-positive pre-B cell lines that are able to differentiate into immature B cells in vitro. Antibody cross-linking of the pre-BCR induced apoptosis and differentiation accompanied with tyrosine phosphorylation. A specific tyrosine-phosphorylated 43 kDa protein (p43) was found down-stream of the pre-BCR. The results demonstrated the receptor function of pre-BCR, which indicates that a ligand-like molecule or a cross-linking structure on the cell surface is possibly present.
Keywords: apoptosis, gene rearrangement, pre-B cell receptor, surrogate light chain, tyrosine phosphorylation
