Protein Name:
Immunoglobulin J chain
|
UniprotKB/SwissProt ID: P01591 (P01591)
Gene Name:
JCHAIN
Organism: Homo sapiens (Human)
Function: 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 dimers and/or larger polymers. It also helps to bind these immunoglobulins to secretory component
