About: Hya RNA motif

The hya RNA motif is a conserved RNA structure that was discovered by bioinformatics.hya motif RNAs are found in Actinomycetota. hya motif RNAs likely function as cis-regulatory elements, in view of their positions upstream of protein-coding genes.Indeed, the RNAs are upstream of multiple genes that encode non-homologous proteins. If all examples of the RNA were upstream of homologous genes, there is the possibility that the RNAs were conserved in that position simply by inheritance. The non-homology of the genes downstream of hya RNAs makes this scenario less likely. The genes presumably regulated by hya RNAs are subunits of nickel-iron hydrogenase I.
