Antibodies have two shorter proteins {light chain}. Light chains have variable regions at arm ends, joining region, and constant region. Single genes are for constant regions. Light chains can come from five joining-region genes. Thousands of genes code for variable regions. How regions bind together also varies. Light chains parallel Y arms on outsides. Light chains have two types: kappa or lambda.
