Secondary structure prediction of mammalian Lipocalin UTRs.

(A) Comparison of the number of alternative UTR secondary structures of Lipocalins with those of structural RNAs of similar length compiled in the Rfam database. (B) Secondary structure prediction of 5’ UTRs of human Lipocalins. The structure with minimal folding energy (MFE) is shown for each Lipocalin. The elements shown in red represent regions showing similarity to the MFE structure in at least 60% of the suboptimal (± 5 Kcal/mol) structures. 5’ end is denoted by a star and 3’end by a dot.
