Description
Product Characteristics:
Death Associated Protein 5 (DAP5) is a 97 kDa protein with high amino acid sequence homology to Eukaryotic Translation Initiation Factor 4G (eIF4G). Compared with eIF4G, DAP5 lacks the N-terminal region necessary for cap-dependent translation and has a unique C-terminal part functioning as a regulator for interferon-gamma induced cell death. During apoptosis, DAP5 is cleaved at Asp790. The C-terminal truncated form of DAP5 functions as a cap-independent translation initiation factor responsible for the mediation of its own translation during apoptosis.
Subcellular location: Cytoplasm
Synonyms: Death Associated Protein-5, Death associated protein 5, Eukaryotic translation initiation factor 4 gamma 2, Nat1, Novel APOBEC-1 target 1, Translation repressor NAT1.
Target Information: Translation initiation is mediated by specific recognition of the cap structure by eukaryotic translation initiation factor 4F (eIF4F), which is a cap binding protein complex that consists of three subunits: eIF4A, eIF4E and eIF4G. The protein encoded by this gene shares similarity with the C-terminal region of eIF4G that contains the binding sites for eIF4A and eIF3\, eIF4G, in addition, contains a binding site for eIF4E at the N-terminus. Unlike eIF4G, which supports cap-dependent and independent translation, this gene product functions as a general repressor of translation by forming translationally inactive complexes. In vitro and in vivo studies indicate that translation of this mRNA initiates exclusively at a non-AUG (GUG) codon. Alternatively spliced transcript variants encoding different isoforms of this gene have been described. [provided by RefSeq, Jul 2008]
