May inform cardiac mRNA translation studies; leaves open relevance to human disease pending validation.
Helicase complexes formed by eIF-4F and eIF-4B on duplex RNA translocate processively in an ATP-dependent manner to melt secondary structure, representing intermediates in mRNA unwinding prior to ribosome binding.
Jaramillo et al. (1991) studied this question.
