Interactioni

Subunit structurei

Homodimer in solution. Component of RNase P which consists of a catalytic RNA component and at least 5 protein subunits. Forms a heterotetrameric subcomplex with Rnp3. Reconstituted enzyme missing individual protein subunits is suboptimally active, showing each subunit contributes to optimization of activity.4 Publications

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
