    basic FUNCTION
  • may contribute to insulin resistance in glucose uptake in type 2 diabetes
  • involved in its regulation of integrin activation
  • death effector domain-containing protein, which is involved in the regulation of apoptotic cell death
  • involved in astrocytic protection against deleterious effects of TNF
  • can redirect the biological outcome of MAP kinase signaling by regulating the subcellular localization of ERK MAP kinase
  • controlling glucose uptake
  • protects glioblastoma cells from glucose deprivation-induced apoptosis via the ERK/MAP kinase pathway
  • functions as a scaffold to enhance ERK activation of RSK2, and this activity is regulated by phosphorylation
  • promotes autophagy in glioma cells in a JNK-dependent manner
  • in addition to apoptosis, is involved in the regulation of other major cellular functions, including cell adhesion, migration, proliferation and glucose metabolism
  • blocks ERK-dependent gene transcription and inhibits proliferation by sequestering ERK in the cytoplasm (
  • not only suppresses ERK signaling and tumorigenesis but also alternatively enhances tumorigenesis in the context of active HRAS
  • CELLULAR PROCESS cell life, antiapoptosis

    INTERACTION

    protein
  • Fas (TNFRSF6)-associated via death domain, FADD and FADD-like ICE, FLICE
  • phospholipase D1, PLD1 and phospholipase D2, PLD2
  • blocks ERK MAP kinase
  • ribosomal S6 kinase 2, RSK2
  • Protein kinase B/Akt
  • HtrA serine peptidase 2, HTRA2
  • phospholipase D1, PLD1
  • PEA15 phosphorylation by PLCG1 is required for PDGFA-induced ERK1/2 nuclear translocation
  • molecular interaction of PEA15 with RPSA (PEA15 ability to induce cell responses to ECM-derived signals through interaction with RPSA may be of crucial importance for tumour cell survival in a poor microenvironment, thus favouring the metastatic spread and colonization)
  • positively regulates HRAS/ERK signaling and increases the proliferation of HRas-transformed epithelial cells through enhanced PLD1 expression and activation
  • cell & other
