Gene: Jchain (joining chain of multimeric IgA and IgM) Rattus norvegicus
Symbol: Jchain
Name: joining chain of multimeric IgA and IgM
Description: 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 protein oligomerization. Predicted to localize to the 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); INTERACTS WITH (+)-schisandrin B; 17beta-estradiol; 7,12-dimethyltetraphene.
Type: gene
RefSeq Status: MODEL
