HgcE RNA
In the world of genes, there's one so rare,
Pf3 RNA, beyond compare.
Found in hyperthermophiles, so hot,
Its name was HgcE, but now it's not.
Pf3, a snoRNA, so small and neat,
It snoozes on H/ACA, a cozy seat.
With K-turn motifs, it dances along,
Targeting 23S rRNA, a melodious song.
Once known as HgcE, a name so grand,
But Pf3 it became, a change so unplanned.
Non-coding it may be, but oh so wise,
Pseudouridylation, its secret disguise.
Pab105, another name it claims,
With rRNA targets, it plays its games.
A whimsical snoRNA, with a mission clear,
To guide the genes, without any fear.
So let's celebrate Pf3, our star of the show,
A gene so special, we all want to know.
In the world of science, it shines so bright,
Pf3 RNA, a source of delight.
