The p52 NF-kB subunit is induced through activation of the alternative (noncanonical) NF-kB pathway in response to a range of stimuli such as lymphotoxin-b, BAFF and CD40, as well as DNA damage. The p52 formation results from proteolytic processing of its precursor protein p100 as a consequence of IKKalpha-mediated phosphorylation. The p52 is most commonly found as a heterodimer with RelB, although other dimer combinations have been identified by ChIP analysis. Ser222 of NF-kappa B p52 is phosphorylated by the kinase GSK3beta. Phosphorylation at S222 appears to regulate not only p52 partner dimerization but also the p52 dependent activation or repression of Skp2 gene expression.
