Figure 2. MALT1-API2 interacts with BCL10 via the MALT1 Ig-like domains.

Figure 2

A, Inclusion of one or two Ig-like domains of MALT1 in MALT1-API2 allows the binding of endogenous BCL10 in HEK-293T. Immunoblot with α-TRAF6, α-BCL10 and α-Flag on protein complexes co-precipitated with Flag-bio-tagged M2A8, M4A8, M7A8, M8A8 and MALT1, transiently expressed in HEK-293T cells. B, M4A8 binds endogenous BCL10 in SSK41 B-cells. Immunoblot with α-BCL10 and α-Flag on protein complexes pulled down with Flag-bio-tagged M4A8 stably expressed in SSK41-BirA B-cells. Precipitated protein complexes from two different SSK41-BirA-M4A8 clones (69 and 93) were compared to the protein complex from HEK-293T cells with transient overexpression of M4A8. Molecular weight standards are in kDa.
