背景信息

Recombinant human IGLV2-14 protein is a genetically engineered variant of the immunoglobulin lambda variable 2-14 (IGLV2-14) chain, a component of antibody light chains. The IGLV2-14 gene, located on chromosome 22q11.2. encodes the variable domain of the lambda light chain, which contributes to antigen-binding specificity in B cell receptors (BCRs) and antibodies. This locus is part of the immunoglobulin lambda gene cluster, known for its role in generating antibody diversity through V-J recombination and somatic hypermutation. IGLV2-14 is expressed during B cell development and is implicated in forming diverse antibody repertoires critical for adaptive immunity.

Recombinant IGLV2-14 is typically produced in heterologous systems (e.g., E. coli, mammalian cells) for structural and functional studies. Its production enables detailed analysis of antigen interactions, antibody paratope formation, and light chain contributions to immune responses. Research on this protein provides insights into antibody engineering, autoimmune disorders (where aberrant IGLV segments may contribute to self-reactivity), and B cell malignancies. Additionally, recombinant IGLV2-14 serves as a tool for studying genetic variations, somatic mutations, and their effects on antibody affinity or pathogenicity. Its applications extend to therapeutic antibody development, particularly in optimizing synthetic antibodies for enhanced specificity or reduced immunogenicity.
