CC   -!- FUNCTION: Probable non-functional open reading frame (ORF) of V region
CC       of the variable domain of immunoglobulin light chains
CC       (PubMed:24600447). Non-functional ORF generally cannot participate in
CC       the synthesis of a productive immunoglobulin chain due to altered V-
CC       (D)-J or switch recombination and/or splicing site (at mRNA level)
CC       and/or conserved amino acid change (protein level) (PubMed:9619395).
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:22158414, PubMed:20176268). 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:20176268, PubMed:17576170).

CC       ECO:0000303|PubMed:9619395}.
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 IGKV1D-42*02. {ECO:0000305}.
CC   -!- CAUTION: Most probably a non-functional protein that cannot participate
CC       in the synthesis of a productive immunoglobulin chain due to an unusual
CC       recombination signal (RS) sequence altering V-(D)-J recombination
CC       (PubMed:9619395). {ECO:0000303|PubMed:9619395, ECO:0000305}.
