由該基因編碼的蛋白質使抑制劑/nf-kappa-b復合物磷酸化，導致抑制劑離解和nf-kappa-b活化。編碼的蛋白質本身存在于蛋白質復合物中。已經發現了一些轉錄變體，有些是蛋白質編碼的，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]
