We also identified 4 hnRNP-E2 MAPKERK1/2 phosphorylation sites and demonstrated that hnRNP-E2 is a bona fide MAPKERK1/2 substrate and that MAPKERK1/2-dependent phosphorylation of hnRNP-E2 at these amino acid residues is essential for increased hnRNP-E2 expression in BCR/ABL-expressing cells. Serine/threonine to alanine substitution abolishes hnRNP-E2 phosphorylation and markedly decreases its stability in BCR/ABL-expressing myeloid precursors. Consistent with the existence of a BCR/ABL-MAPK pathway that posttranslationally regulates hnRNP-E2 expression, sequence analysis of hnRNP-E2 revealed the presence of 4 consensus ERK phosphorylation sites (S/T-P)35,36 at amino acid residues 173, 189, 213, and 272 (Figure 2B). |

Only AIP4 associated with PCBP2 and caused MAVS degradation. The interaction between PCBP2 and AIP4 was abrogated when the linker region or WB2 of PCBP2 was deleted, which confirmed our previous data indicating that this region was critical for PCBP2-mediated degradation of MAVS |
