Anti-NF-kB p65 (Ser316) Antibody

p65, also known as RelA, is one of the five members of the NF-kB family. The p65 and p50 heterodimer is the predominant form of NF-kB, where p65 is the major subunit (Gilmore et al, 2006). There have been 13 identified phosphorylation sites on p65, including Ser-316 which is induced by IL-1β (Viatour et al, 2005 and Wang et al, 2015). Phosphorylation of Ser-316 is essential for NF-kB nuclear transportation, NF-kB-dependent gene regulation, cytokine/chemokine secretion, and other biological functions (Wang et al, 2015). Ser-316 has also been demonstrated to co-phosphorylate with either Ser-529 or Ser-536 to regulate the majority of NF-kB targeted genes while having its own unique regulation function (Wang et al, 2015). CKI kinase specifically targets phosphorylation at Ser-316 on p65 (Wang et al, 2015). CKI is involved in regulation of membrane transport, cell division, DNA repair, and nuclear localization by phosphorylating its target proteins (Price et al, 2006).
