IkappaBalpha (20-39) (human) (trifluoroacetate salt)

IkappaBalpha (20-39) is a peptide fragment of the N-terminal signal-receiving domain of IkappaBalpha (Cay-43691), which is an inhibitor of NF-kappaB and a member of the IkappaB family of proteins. It contains several post-translational modification sites that regulate IkappaBalpha activity, including the phosphorylation sites Ser32 and Ser36, the ubiquitination sites Lys21 and Lys22, and the SUMOylation sites Lys21 and Lys38.
