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

CC   -!- SUBUNIT: Immunoglobulins are composed of two identical heavy
CC       chains and two identical light chains; disulfide-linked.
