Although beta-arrestin 2 deficiency did not affect LPA induced IKKalpha/beta phosphorylation, it impaired LPA induced IKK kinase activity, which is consistent with our previous findings that CARMA3 is required for IKKalpha/beta activation but not for the inducible phosphorylation of IKKalpha/beta

Furthermore, knockdown of PP2Ac expression enhances LPA induced MEKK3 mediated IkappaB kinase beta (IKKbeta) phosphorylation and NF-kappaB activation
