Figure 1. Models for HuD-mediated translation enhancement.
(A) General translation enhancement. This model proposes that HuD functions as an autonomous translation activator through its interactions with eIF4A and the poly(A) tail.
(B) Transcript-specific translation enhancement. This model proposes that HuD first associates with mRNA targets through binding to AU-rich or U-rich sequences (e.g., ARE) in the 3' UTRs to exert its translation enhancing effect.
