Protein

Immunoglobulin J chain

Gene

JCHAIN

Organism
Oryctolagus cuniculus (Rabbit)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

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.By similarity
