Interleukins -4 and -13 signature





Description

Interleukin-4 (IL-4) [1,2] is a cytokine that plays a central role in the control and regulation of the immune and inflammatory system. IL-4 is a participant in several B-cell activation processes. It also stimulates other cell types such as T cells or mast cells. IL-4 is a glycoprotein of 110 to 131 residues. It contains three disulfide bonds. The position of these disulfide bonds is not highly conserved since the topology of two of them differs in Human and mouse IL-4 [3].

Interleukin-13 [4] (IL-13) is a recently discovered pleiotropic cytokine which may be important in the regulation of the inflammatory and immune responses. IL-13 is a glycoprotein of 110 residues.

The sequence of IL-4 and IL-13 are distantly related. As a signature pattern we selected the best conserved region which is located in the N-terminal part of these proteins. This region contains a cysteine which, in IL-4, is involved in the sole disulfide bond conserved between human and mouse IL-4.
