Hypothetical Proteins [HP] are the transcripts predicted to be expressed in an organism but no
evidence of it exists in gene banks. On the other hand, long non-coding RNAs [lncRNAs] are the
transcripts that might be present in the 5’ UTR or intergenic regions of the genes whose length
are above 200 bases. With the known unknown [KU] regions in the genomes rapidly existing in
gene banks, there is a need to understand the role of open reading frames in context of
annotation. In this commentary, we emphasize that HPs could indeed be the predecessors of
lncRNAs.
