由该基因编码的蛋白质使抑制剂/nf-kappa-b复合物磷酸化，导致抑制剂离解和nf-kappa-b活化。编码的蛋白质本身存在于蛋白质复合物中。已经发现了一些转录变体，有些是蛋白质编码的，有些不是。[由RefSeq提供，2011年9月]
The protein encoded by this gene phosphorylates the inhibitor in the inhibitor/NF-kappa-B complex, causing dissociation of the inhibitor and activation of NF-kappa-B. The encoded protein itself is found in a complex of proteins. Several transcript variants, some protein-coding and some not, have been found for this gene. [provided by RefSeq, Sep 2011]
