Y011255 by MBP is a rabbit polyclonal antibody detecting RelB (RELB) phosphorylated at Serine 552, a GSK-3β-dependent phosphorylation that, together with pThr84, triggers proteasomal degradation of RelB as a negative feedback terminator of non-canonical NF-κB signalling. Apparent MW ~68 kDa (anomalous migration). Validated for WB, IHC, IF, and ELISA. Human and mouse. Research Use Only.
