1 Interestingly, the association of c-Abl with IkappaBalpha, which is detectable in the form of nonphosphorylated proteins, is remarkably enhanced by an inducible binding of tyrosine-phosphorylated IkappaBalpha to the c-Abl SH2 domain. Tyrosine NFKB inhibitor alpha Homo sapiens
2 Interestingly, the association of c-Abl with IkappaBalpha, which is detectable in the form of nonphosphorylated proteins, is remarkably enhanced by an inducible binding of tyrosine-phosphorylated IkappaBalpha to the c-Abl SH2 domain. Tyrosine NFKB inhibitor alpha Homo sapiens
3 In contrast to the serine 32/34 phosphorylation that triggers ubiquitination and degradation of IkappaBalpha, c-Abl-mediated phosphorylation at tyrosine 305 is associated with an increase of the IkappaBalpha protein stability. Tyrosine NFKB inhibitor alpha Homo sapiens
