{"symbol":"JCHAIN","synonyms":["IGJ","IGCJ","JCH"],"name":"joining chain of multimeric IgA and IgM","description":"Enables IgA binding activity and protein homodimerization activity. Contributes to several functions, including immunoglobulin receptor binding activity; peptidoglycan binding activity; and phosphatidylcholine binding activity. Involved in several processes, including glomerular filtration; innate immune response; and positive regulation of respiratory burst. Located in extracellular space. Part of monomeric IgA immunoglobulin complex; pentameric IgM immunoglobulin complex; and secretory dimeric IgA immunoglobulin complex.
