Expression of ER proteins and Ig chains in LPS-stimulated wild-type and ATF6α-deficient B cells. Splenic B cells were isolated from Atf6a+/+ and Atf6a−/− mice and cultured in the presence of LPS for the indicated intervals. Immunoblotting was performed for the ER proteins BiP/GRP78 and GRP94, the ER translocon component TRAPα, Ig μ heavy and κ light chains, ATF6α(P) as an internal control for genotyping and β-actin as a control for loading and sample integrity. Data are from a representative experiment out of three repeats.
