EEF 1 A 1 ( eukaryotic translation elongation factor 1 alpha 1 )
The main processed mRNA encompasses exons 1, 2, 3, 4, 5, 6, 7, 8, this last can be in short or long form. In a few cases also exon 1' is retained. In a few cases exons 1 (and 1') are substituted by the alternative exon from a putative upstream minor promoter, as described above. Moreover, a quite high number of processed transcripts that, after exons 1 and 2, retain intron 2, which introduces a...
متن کاملProtein isoprenylation in Trypanosoma brucei brucei.
Trypanosoma brucei is a digenetic protozoan parasite presenting a public health hazard in certain areas of Africa; it is transmitted between mammals (bloodstream form (BSF)) by tsetse flies (procyclic form (PCF)). We have an ongoing interest in small GTP proteins in T. brucei, and these are commonly isoprenylated. Many isoprenylated proteins belong to the rab family and include ras; the isopren...
متن کاملTranslation elongation factor 1-alpha interacts specifically with the human immunodeficiency virus type 1 Gag polyprotein.
Human immunodeficiency virus type 1 (HIV-1) gag-encoded proteins play key functions at almost all stages of the viral life cycle. Since these functions may require association with cellular factors, the HIV-1 matrix protein (MA) was used as bait in a yeast two-hybrid screen to identify MA-interacting proteins. MA was found to interact with elongation factor 1-alpha (EF1alpha), an essential comp...
متن کاملEukaryotic Translation Elongation Factor 1-Alpha 1 Inhibits p53 and p73 Dependent Apoptosis and Chemotherapy Sensitivity
The p53 family of transcription factors is a key regulator of cell proliferation and death. In this report we identify the eukaryotic translation elongation factor 1-alpha 1 (eEF1A1) to be a novel p53 and p73 interacting protein. Previous studies have demonstrated that eEF1A1 has translation-independent roles in cancer. We report that overexpression of eEF1A1 specifically inhibits p53-, p73- an...
متن کاملA Structural Domain Mediates Attachment of Ethanolamine Phosphoglycerol to Eukaryotic Elongation Factor 1A in Trypanosoma brucei
Ethanolamine phosphoglycerol (EPG) represents a protein modification that so far has only been found in eukaryotic elongation factor 1A (eEF1A). In mammals and plants, EPG is covalently attached to two conserved glutamate residues located in domains II and III of eEF1A. In contrast, Trypanosoma brucei eEF1A contains a single EPG attached to Glu362 in domain III. The sequence and/or structural r...
