    SUBCELLULAR LOCALIZATION     intracellular
    text perinuclear region
    basic FUNCTION
  • inhibitor of apoptosis through inhibiting the activation of p38 MAP kinase
  • multifunctional regulator
  • activating protein kinase C, multifunctional regulator of the cell signaling processes mediated by both kinases
  • enzymes important for N6-methyladenosine RNA transmethylation (METTL4, YWHAB, and YTHDF3), regulates the pace of the circadian clock
  • CELLULAR PROCESS cell life, antiapoptosis
    PHYSIOLOGICAL PROCESS nervous system
    a component
  • 14-3-3 dimer binds tightly to single molecules containing tandem repeats of phosphoserine motifs and molecules such as Raf, BAD and Cbl
  • AKIRIN2-YWHAB complex could act as a transcriptional silencer, and MAPK1 was one of the target genes of the AKIRIN2-YWHAB complex
    small molecule
  • p38 MAP kinase
  • ITGB1 for regulation of integrin-mediated cell adhesion and signaling events
  • the TSC1-TSC2 complex and negatively regulate the function of the TSC proteins
  • SSH1
  • interaction with ATXN1, YWHAE, YWHAH, YWHAZ mediated by AKT1 to modulate the neurotoxicity of SCA1
  • interacting with AKIRIN2
  • phosphorylation-dependent interaction between YWHAB and SPTAN1 acts as a switch between positive and negative regulation of neurite outgrowth stimulated by NCAM
  • interacts with DACT1 (YWHAB binding attenuates the ability of hDpr1 to promote Dishevelled (Dvl) degradation, thus enhancing Wnt signaling)
  • YWHAB binding to phosphorylated CFTR augments its biogenesis by reducing retrograde retrieval of CFTR to the endoplasmic reticulum
  • YWHAB is absolutely required for KCNK3 internalization, a role heretofore not described for a 14-3-3 protein
  • interactors of GCGR, LDLR and TMED2, significantly enhanced glucagon-stimulated glucose production, while YWHAB inhibited glucose production
  • interaction of DAPK2 with ACTN1 was localized at the plasma membrane, resulting in massive membrane blebbing and reduced cellular motility, whereas the interaction of DAPK2 with YWHAB was localized to the cytoplasm, with no impact on blebbing, motility, or viability
