 The study found that RNA-bound proteins are much more diverse in mammalian organs compared to those in cultured cells. This suggests that there may be unique mechanisms involved in regulating gene expression in each organ. Additionally, the study discovered that many of the RNA-bound proteins were enzymes that utilized nucleotides as cofactors, indicating a strong connection between gene expression and metabolism.
