Jchain - joining chain of multimeric IgA and IgM

Predicted to enable IgA binding activity; protein homodimerization activity; and protein-macromolecule adaptor activity. Predicted to contribute to several functions, including immunoglobulin receptor binding activity; peptidoglycan binding activity; and phosphatidylcholine binding activity. Predicted to be involved in several processes, including defense response to other organism; glomerular filtration; and positive regulation of respiratory burst. Predicted to be located in extracellular space. Predicted to be part of monomeric IgA immunoglobulin complex; pentameric IgM immunoglobulin complex; and secretory dimeric IgA immunoglobulin complex. Orthologous to human JCHAIN (joining chain of multimeric IgA and IgM). [provided by Alliance of Genome Resources, Apr 2022]
