CC -!- FUNCTION: V region of the variable domain of immunoglobulin light
CC chains that participates in the antigen recognition (PubMed:24600447).
CC Immunoglobulins, also known as antibodies, are membrane-bound or
CC secreted glycoproteins produced by B lymphocytes. In the recognition
CC phase of humoral immunity, the membrane-bound immunoglobulins serve as
CC receptors which, upon binding of a specific antigen, trigger the clonal
CC expansion and differentiation of B lymphocytes into immunoglobulins-
CC secreting plasma cells. Secreted immunoglobulins mediate the effector
CC phase of humoral immunity, which results in the elimination of bound
CC antigens (PubMed:20176268, PubMed:22158414). The antigen binding site
CC is formed by the variable domain of one heavy chain, together with that
CC of its associated light chain. Thus, each immunoglobulin has two
CC antigen binding sites with remarkable affinity for a particular
CC antigen. The variable domains are assembled by a process called V-(D)-J
CC rearrangement and can then be subjected to somatic hypermutations
CC which, after exposure to antigen and selection, allow affinity
CC maturation for a particular antigen (PubMed:17576170, PubMed:20176268).
CC {ECO:0000303|PubMed:17576170, ECO:0000303|PubMed:20176268,
CC ECO:0000303|PubMed:22158414, ECO:0000303|PubMed:24600447}.
CC -!- SUBUNIT: Immunoglobulins are composed of two identical heavy chains and
CC two identical light chains; disulfide-linked.
CC {ECO:0000303|PubMed:20176268}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000303|PubMed:20176268,

CC {ECO:0000303|PubMed:20176268, ECO:0000303|PubMed:22158414}.
CC -!- POLYMORPHISM: There are several alleles. The sequence shown is that of
CC IMGT allele IGLV2-23*01 and IMGT allele IGLV2-23*03.
CC -!- CAUTION: For an example of a full-length immunoglobulin lambda light
CC chain see AC P0DOX8. {ECO:0000305}.
