• V region variable domain of immunoglobulin light chains
• variable domains are assembled by V-(D)-J rearrangement & can then be subjected to somatic hypermutations which, after exposure to antigen & selection, allow affinity maturation for a particular antigen

Compartment

secreted

Polymorphism
