== Gene Information ==
* **Official Symbol**: JCHAIN
* **Official Name**: joining chain of multimeric IgA and IgM

== Function Summary ==
* **Entrez Summary**: N/A
* **UniProt Summary**: Serves to link two monomer units of either IgM or IgA. In the case of IgM, the J chain-joined dimer is a nucleating unit for the IgM pentamer, and in the case of IgA it induces larger polymers. It also help to bind these immunoglobulins to secretory component. {ECO:0000250|UniProtKB:P01592}.
