Abstract Synonym(s): cytokine, intecrine

Many low-molecular weight factors secreted by cells including fibroblasts, macrophages and endothelial cells, in response to a variety of stimuli such as growth factors, interferons, viral transformation and bacterial products, are structurally related [PubMed1910690, PubMed2149646, PubMed2687068]. Most members of this family of proteins seem to have mitogenic, chemotactic or inflammatory activities. These small cytokines are also called intercrines or chemokines. They are cationic proteins of 70 to 100 amino acid residues that share four conserved cysteine residues involved in two disulphide bonds, as shown in the following schematic representation: 

                             +------------------------------------+
                             |                                    |
     xxxxxxxxxxxxxxxxxxxxxxCxCxxxxxxxxxxxxxxxxxxxxxxxCxxxxxxxxxxxxCxxxxx
                           |                         |
                           +-------------------------+

'C': conserved cysteine involved in a disulphide bond.

These proteins can be sorted into two groups based on the spacing of the two amino-terminal cysteines. In the first group (see ), the two cysteines are separated by a single residue (C-x-C), while in the second group (see ), they are adjacent (C-C).

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 44 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 Interleukin 8-like chemokines 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 44 hidden Markov models representing the Interleukin 8-like chemokines superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
