S1_RNase_E: RNase E and RNase G, S1-like RNA-binding domain. RNase E is an essential endoribonuclease in the processing and degradation of RNA. In addition to its role in mRNA degradation, RNase E has also been implicated in the processing of rRNA, and the maturation of tRNA, 10Sa RNA and the M1 precursor of RNase P. RNase E associates with PNPase (3' to 5' exonuclease), Rhl B (DEAD-box RNA helicase) and enolase (glycolytic enzyme) to form the RNA degradosome. RNase E tends to cut mRNA within single-stranded regions that are rich in A/U nucleotides. The N-terminal region of RNase E contains the catalytic site. Within the conserved N-terminal domain of RNAse E and RNase G, there is an S1-like subdomain, which is an ancient single-stranded RNA-binding domain. S1 domain is an RNA-binding module originally identified in the ribosomal protein S1. The S1 domain is required for RNA cleavage by RNase E. RNase G is paralogous to RNase E with an N-terminal catalytic domain that is highly homologous to that of RNase E. RNase G not only shares sequence similarity with RNase E, but also functionally overlaps with RNase E. In Escherichia coli, RNase G is involved in the maturation of the 5' end of the 16S rRNA. RNase G plays a secondary role in mRNA decay.

Tips:  If you've navigated here from a protein, hovering over a position on the weblogo will display the corresponding protein position for that domain position. The histograms below the weblogo indicate mutations found on the domain. Red is for disease (OMIM) and blue is for SNPs. Functional Features are displayed as orange boxes under the histograms. You can choose which features are displayed in the box below. Range on the Protein: Protein ID Protein Position Domain Position:
