DnaX ribosomal frameshifting element explained

DnaX ribosomal frameshifting element
Symbol:	DnaX
Rfam:	RF00382
Rna Type:	Cis-reg frameshift_element
Tax Domain:	Bacteria

The DnaX ribosomal frameshifting element is a RNA element found in the mRNA of the dnaX gene in E. coli. The dnaX gene has two encoded products, tau and gamma, which are produced in a 1:1 ratio. The gamma protein is synthesised due to programmed frameshifting and is shorter than tau. The two products of the dnaX gene are DNA polymerase III subunits.^{[1] [2]}
