Human Interleukin-31 (IL-31) is a 24 kDa, short-chain member of the alpha -helical family of cytokines. The human IL-31 cDNA encodes a 164 amino acid (aa) precursor that contains a 23 aa signal peptide and a 141 aa mature protein. The mature region shows four alpha -helices which would be expected to show a typical […]

IFN λ1, 2, and 3 (also known as IL-29, IL-28A and IL-28B respectively) are distantly related to the IL-10 family and the interferons. All three IFN-lambdas use a distinct receptor system composed of an IFN-λR1 subunit (also called CRF2-12) and IL-10R2 subunit (also called CRF2-14). Signaling through this receptor system induces antiviral defenses similar to, […]

IL-28B (also named interferon-lambda 3, IFN-lambda 3), IL-28A (IFN-lambda 2) and IL-29 (IFN-lambda 1) are type III interferons that are class II cytokine receptor ligands. They are distantly related to members of the IL-10 family and type I IFN family. Human IL-28B cDNA encodes a 200 amino acid (aa) protein with a 25 aa signal […]

SF-20, or MYDGF, is a Bone marrow-derived monocyte protein, and it is correlated with enhanced metabolic activity, suppression of apoptosis, and stimulation of cell proliferation. MYDGF is expressed predominantly in inflammatory cells, such as monocytes and macrophages. Up-regulation of MYDGF expression was also found during adipocyte differentiation. Expression of MYDGF was induced in the circulation […]

IL28A (Interferon-lambda 2; IFN-lambda 2), IL-28B/IFN-lambda 3, and IL-29/IFN-lambda 1 are type III interferons which are distantly related to IL-10 family and type I IFN family cytokines. Mature human IL-28A is an approximately 22-25 kDa protein that shares 66% amino acid (aa) sequence identity with mouse and rat IL-28A and shows cross-species activity. It shares […]

Interleukin-22 (IL-22), also known as IL-10-related T cell-derived inducible factor (IL-TIF), was initially identified as a gene induced by IL-9 in mouse T cells and mast cells. It belongs to the IL-10-related cytokine family that consists of six members (IL-10, IL-19, IL-20, IL-22, IL-24/MDA-7, and IL-26/AK155). These proteins share structural homology and some degree of […]

Interleukin-22 (IL-22), also known as IL-10-related T cell-derived inducible factor (IL-TIF) was initially identified as a gene induced by IL-9 in mouse T cells and mast cells. Human IL-22 cDNA encodes a 179 amino acid (aa) residue protein with a putative 33 aa signal peptide that is cleaved to generate a 147 aa mature protein […]

Interleukin-21 (IL-21) is an approximately 14 kDa four-helix-bundle cytokine in the family of cytokines that utilize the common gamma chain (gamma c) as a receptor subunit. Mature mouse IL-21 shares 66%, 59%, 58%, and 88% aa sequence identity with mature canine, human, rabbit, and rat IL-21, respectively. It can induce target cells division or proliferation. […]

Hunan IL-21 protein is a molecule that is found in the immune system of individuals. It is a type of interleukin, which is a protein that helps in the communication between immune cells. IL-21 plays a crucial role in regulating the body’s immune response, specifically in the development, differentiation, and function of certain immune cells, […]
