Facts about MAP kinase-activated protein kinase 5.
Acts as a tumor suppressor by mediating Ras- induced senescence and phosphorylating p53/TP53. Involved in post- transcriptional regulation of MYC by mediating phosphorylation of FOXO3: phosphorylation of FOXO3 leads to promote nuclear localization of FOXO3, enabling expression of miR-34b and miR-34c, two post-transcriptional regulators of MYC that bind to the 3'UTR of MYC transcript and prevent MYC translation.

Expressed ubiquitously.
Cytoplasm. Nucleus. Translocates to the cytoplasm following phosphorylation and activation. Interaction with ERK3/MAPK6 or ERK4/MAPK4 and phosphorylation at Thr-182, activates the protein kinase activity, followed by translocation to the cytoplasm. Phosphorylation by PKA/PRKACA at Ser-115 also induces nuclear export.
