Immunoglobulin J chain (IPR024110)

Short name: Ig_J

Family relationships

None.

Description

Immunoglobulin J 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 the secretory component [PMID: 10972899].
