Abstract

Synonym(s): Rsp5 or WWP domain

The WW domain is a short conserved region in a number of unrelated proteins, which folds as a stable, triple stranded beta-sheet. This short domain of approximately 40 amino acids, may be repeated up to four times in some proteins [PubMed7846762, PubMed7802651, PubMed7828727, PubMed7641887]. The name WW or WWP derives from the presence of two signature tryptophan residues that are spaced 20-23 amino acids apart and are present in most WW domains known to date, as well as that of a conserved Pro. The WW domain binds to proteins with particular proline-motifs, [AP]-P-P-[AP]-Y, and/or phosphoserine- phosphothreonine-containing motifs [PubMed7644498, PubMed11911877]. It is frequently associated with other domains typical for proteins in signal transduction processes.

A large variety of proteins containing the WW domain are known. These include; dystrophin, a multidomain cytoskeletal protein; utrophin, a dystrophin-like protein of unknown function; vertebrate YAP protein, substrate of an unknown serine kinase; Mus musculus (Mouse) NEDD-4, involved in the embryonic development and differentiation of the central nervous system; Saccharomyces cerevisiae (Baker's yeast) RSP5, similar to NEDD-4 in its molecular organization; Rattus norvegicus (Rat) FE65, a transcription-factor activator expressed preferentially in liver; Nicotiana tabacum (Common tobacco) DB10 protein and others.

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 17 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 WW domain 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 17 hidden Markov models representing the WW domain superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
