    SUBCELLULAR LOCALIZATION     intracellular
    basic FUNCTION
  • promoting the transfer of aminoacylated tRNA to the A site of the ribosome
  • oncogenicity of eEF1A2 may be related either to its role in protein synthesis or to potential non-canonical functions
  • regulates oncogenesis through AKT1 and PI3K-dependent cytoskeletal remodeling
  • might play an important role in pancreatic carcinogenesis, possibly by acting as a tumour oncogene
  • important role for EEF1A2 in driving cap-independent translation of utrophin A in skeletal muscle
  • PI4KB, EEF1A2 and PI(4)P likely play an important role in mammary neoplasia and acinar development
  • is involved in protein synthesis, suppression of apoptosis, and regulation of actin function and cytoskeletal structure
  • plays an important role in prostate cancer development, especially in inhibiting apoptosis
  • both EEF1A1 and EEF1A2 colocalise with all EEF1B2 subunits, in such close proximity that they are highly likely to be in a complex
  • stimulates the phospholipid signaling and activates the AKT1 -dependent cell migration and actin remodeling that ultimately favors tumorigenesis
  • EEF1A1, and EEF1A2 proteins play a critical role in numerous human diseases through enhancement of oncogenesis, blockade of apoptosis, and increased viral pathogenesis
  • CELLULAR PROCESS cell life, differentiation
    a component
    small molecule
  • translation requires the specific attachment of AAs to AARS and the subsequent delivery of aminoacyl-tRNAs to the ribosome by elongation factor 1 alpha (EEF1A2)
  • interaction between LRRK2 and EEF1A1 and EEF1A2 may reciprocally modulate their physiological function
  • interactions between EEF1A2 and ZPR1 (zinc-finger protein 1), which interacts with the SMN (survival motor neuron) protein, may be important in motor neuron biology
  • EEF1A2 as a novel interacting partner CDKN2A, and interaction of CDKN2A with EEF1A2, and subsequent downregulation of the expression and function of EEF1A2 is a novel mechanism explaining the anti-proliferative effects of CDKN2A
  • interaction with TSPY1, through six lysine residues observed in EEF1A2 suggesting their possible role in TSPY1-EEF1A2 complex formation essential for germ cell development and spermatogenesis
