EEF1D encodes a subunit of the elongation factor-1 complex, which is responsible for the enzymatic delivery of aminoacyl tRNAs to the ribosome. This subunit, delta, functions as guanine nucleotide exchange factor. It is reported that following HIV-1 infection, this subunit interacts with HIV-1 Tat. This interaction results in repression of translation of host cell proteins and enhanced translation of viral proteins. Several alternatively spliced transcript variants encoding multiple isoforms have been found for this gene. Related pseudogenes have been defined on chromosomes 1, 6, 7, 9, 11, 13, 17, 19. EEF1D (Eukaryotic Translation Elongation Factor 1 Delta) is a Protein Coding gene. Diseases associated with EEF1D include Cystic Echinococcosis. Among its related pathways are Influenza A and Viral mRNA Translation.
