Lambda 5 (also called immunoglobulin lambda-like polypeptide 1 or CD179b antigen) and VpreB comprise the surrogate light chain of the pre-B cell receptor complex.
SL chain is also part of a quality control mechanism that tests a μ-chain for its ability to pair with conventional L chains.
It can form Ig-like complexes with the heavy (H) chain, the DHJHC μ-protein or the p55 chain.
Production of the surrogate light chain begins at the stage of pro-B cells, continues during the pre-B cell stage and halts at the immature B cell stage.
Once pre-BCR is expressed, SL chain expression is turned off.
As pre-B II cells proliferate, SL is diluted out, thus limiting pre-BCR formation.
Lambda 5, a 22kDa protein, is critical for B cell development in mammals.
Expression of Lambda 5 is highest in liver, pre-B lymphocytes and bone marrow, the major source of B cell precursors.
