Abstract

Whey acidic protein (WAP) is a major component of the whey fraction of milk, which contains a significant number of different proteins. WAP proteins share limited sequence identity, except for their conserved cysteine-rich regions, known as 4-disulphide core (4-DSC) domains, and the positional conservation of specific residues [PubMed12751894]. Several non-milk proteins also contain 4-DSC patterns, such as certain serine protease inhibitors. WAP itself appears to have a protease-inhibitor function, as seen with its inhibitory effect on the progression of cancer cells [PubMed17215074].

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