Mycoplasma arthritidis-derived mitogen, C-terminal (IPR013997)

Short name: M_arthritidis-der_mitogen_C

Domain relationships



Mycoplasma arthritidis-derived mitogen (MA-Mit) adopts a completely alpha-helical structure consisting of ten alpha helices arranged in two orthogongal bundles. MA-Mit is a superantigen that can activate large fractions of T cells bearing particular TCR V-beta elements. Two MA-Mit molecules form an asymmetric dimer and cross-link two MHC antigens to form a dimerised MA-Mit-MHC complex [PMID: 14962388]. This entry represents the C-terminal alpha-helical bundle domain.
