-!- FUNCTION: V region of the variable domain of immunoglobulin light
chains that participates in the antigen recognition
(PubMed:24600447). Immunoglobulins, also known as antibodies, are
membrane-bound or secreted glycoproteins produced by B
lymphocytes. In the recognition phase of humoral immunity, the
membrane-bound immunoglobulins serve as receptors which, upon
binding of a specific antigen, trigger the clonal expansion and
differentiation of B lymphocytes into immunoglobulins-secreting
plasma cells. Secreted immunoglobulins mediate the effector phase
of humoral immunity, which results in the elimination of bound
antigens (PubMed:20176268, PubMed:22158414). The antigen binding
site is formed by the variable domain of one heavy chain, together
with that of its associated light chain. Thus, each immunoglobulin
has two antigen binding sites with remarkable affinity for a
particular antigen. The variable domains are assembled by a
process called V-(D)-J rearrangement and can then be subjected to
somatic hypermutations which, after exposure to antigen and
selection, allow affinity maturation for a particular antigen
(PubMed:20176268, PubMed:17576170). {ECO:0000303|PubMed:17576170,
ECO:0000303|PubMed:20176268, ECO:0000303|PubMed:22158414,
-!- SUBUNIT: Immunoglobulins are composed of two identical heavy
chains and two identical light chains; disulfide-linked.
-!- SUBCELLULAR LOCATION: Secreted {ECO:0000303|PubMed:20176268,
ECO:0000303|PubMed:22158414}. Cell membrane
{ECO:0000303|PubMed:20176268, ECO:0000303|PubMed:22158414}.
-!- POLYMORPHISM: There are several alleles. The sequence shown is
that of IMGT allele IGKV2-30*01.
-!- CAUTION: For an example of a full-length immunoglobulin kappa
light chain see AC P0DOX7. {ECO:0000305}.
