Abstract

The HR1 repeat was first described as a three times repeated homology region of the N-terminal non-catalytic part of protein kinase PRK1(PKN) [PubMed7851406]. The first two of these repeats were later shown to bind the small G protein rho [PubMed8647255, PubMed9446575] known to activate PKN in its GTP-bound form. Similar rho-binding domains also occur in a number of other protein kinases and in the rho-binding proteins rhophilin and rhotekin. Recently, the structure of the N-terminal HR1 repeat complexed with RhoA has been determined by X-ray crystallography [PubMed10619026]. It forms an antiparallel coiled-coil fold termed an ACC finger.

Browse genome assignments for this superfamily. The SUPERFAMILY hidden Markov model library has been used to carry out SCOP domain assignments to all genomes at the superfamily level.


Alignments of sequences to 2 models in this superfamily are available by clicking on the 'Alignments' icon above. PDB sequences less than 40% identical are shown by default, but any other sequence(s) may be aligned. Select PDB sequences, genome sequences, or paste in or upload your own sequences.


Browse and view proteins in genomes which have different domain combinations including a HR1 repeat domain.


Examine the distribution of domain superfamilies, or families, across the major taxonomic kingdoms or genomes within a kingdom. This gives an immediate impression of how superfamilies, or families, are restricted to certain kingdoms of life.


Explore domain occurrence network where nodes represent genomes and edges are domain architectures (shared between genomes) containing the superfamily of interest.

There are 2 hidden Markov models representing the HR1 repeat superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
