Abstract

The PEBP family is a highly conserved group of proteins that have been identified in numerous tissues in a wide variety of organisms, including bacteria, yeast, nematodes, plants, drosophila and mammals. The various functions described for members of this family include lipid binding, neuronal development [PubMed12492898], serine protease inhibition [PubMed11034991], the control of the morphological switch between shoot growth and flower structures [PubMed10764580], and the regulation of several signalling pathways such as the MAP kinase pathway [PubMed12551925], and the NF-kappaB pathway [PubMed11585904]. The control of the latter two pathways involves the PEBP protein RKIP, which interacts with MEK and Raf-1 to inhibit the MAP kinase pathway, and with TAK1, NIK, IKKalpha and IKKbeta to inhibit the NF-kappaB pathway. Other PEBP-like proteins that show strong structural homology to PEBP include Escherichia coli YBHB and YBCL, the rat neuropeptide HCNP, and Antirrhinum centroradialis CEN.

Structures have been determined for several members of the PEBP-like family, all of which show extensive fold conservation. The structure consists of a large central beta-sheet flanked by a smaller beta-sheet on one side, and an alpha helix on the other. Sequence alignments show two conserved central regions, CR1 and CR2, that form a consensus signature for the PEBP family. These two regions form part of the ligand-binding site, which can accommodate various anionic groups. The N- and C-terminal regions are the least conserved, and may be involved in interactions with different protein partners. The N-terminal residues 2-12 form the natural cleavage peptide HCNP involved in neuronal development. The C-terminal region is deleted in plant and bacterial PEBP homologues, and may help control accessibility to the active site.

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 13 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 PEBP-like 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 13 hidden Markov models representing the PEBP-like superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
