特異性:NF KAPPA B INHIBITOR ALPHA This item is specific for NF-kappa-B inhibitor alpha (NFkBIa, also known as IkB alpha). NFkBIa is one of seven members of the IkB class of inhibitor proteins that have been identified to date. NFkBIa inhibits the NFkB complex in unstimulated cells through non-covalent binding. Following stimulation of cells, NFkBIa is phosphorylated so that it dissociates from the NFkB and then ubiquinated prior to degradation.
