Disease

[DDX6_HUMAN] Note=A chromosomal aberration involving DDX6 may be a cause of hematopoietic tumors such as B-cell lymphomas. Translocation t(11;14)(q23;q32).

Function

[DDX6_HUMAN] In the process of mRNA degradation, may play a role in mRNA decapping. [EDC3_HUMAN] Binds single-stranded RNA. In the process of mRNA degradation, may play a role in mRNA decapping. May play a role in spermiogenesis and oogenesis.^[1] ^[2] ^[3]

Publication Abstract from PubMed

GIGYF (Grb10-interacting GYF [glycine-tyrosine-phenylalanine domain]) proteins coordinate with 4EHP (eIF4E [eukaryotic initiation factor 4E] homologous protein), the DEAD (Asp-Glu-Ala-Asp)-box helicase Me31B/DDX6, and mRNA-binding proteins to elicit transcript-specific repression. However, the underlying molecular mechanism remains unclear. Here, we report that GIGYF contains a motif necessary and sufficient for direct interaction with Me31B/DDX6. A 2.4 A crystal structure of the GIGYF-Me31B complex reveals that this motif arranges into a coil connected to a beta hairpin on binding to conserved hydrophobic patches on the Me31B RecA2 domain. Structure-guided mutants indicate that 4EHP-GIGYF-DDX6 complex assembly is required for tristetraprolin-mediated down-regulation of an AU-rich mRNA, thus revealing the molecular principles of translational repression.
