HS1 functions as an essential actin-regulatory adaptor protein at the immune synapse.

abstract：:Immunoglobulin A (IgA) is prominently secreted at mucosal surfaces and coats a fraction of the intestinal microbiota. However, the commensal bacteria bound by IgA are poorly characterized and the type of humoral immunity they elicit remains elusive.
