Encyclopedia
Suppressor of cytokine signaling 3 is a protein
Protein
Proteins are biochemical compounds consisting of one or more polypeptides typically folded into a globular or fibrous form, facilitating a biological function. A polypeptide is a single linear polymer chain of amino acids bonded together by peptide bonds between the carboxyl and amino groups of...

 that in humans is encoded by the SOCS3 gene
Gene
A gene is a molecular unit of heredity of a living organism. It is a name given to some stretches of DNA and RNA that code for a type of protein or for an RNA chain that has a function in the organism. Living beings depend on genes, as they specify all proteins and functional RNA chains...

Interactions

SOCS3 has been shown to interact
Protein-protein interaction
Protein–protein interactions occur when two or more proteins bind together, often to carry out their biological function. Many of the most important molecular processes in the cell such as DNA replication are carried out by large molecular machines that are built from a large number of protein...

 with PTPN11
PTPN11
Tyrosine-protein phosphatase non-receptor type 11 also known as protein-tyrosine phosphatase 1D or protein-tyrosine phosphatase 2C is an enzyme that in humans is encoded by the PTPN11 gene. PTPN11 is a protein tyrosine phosphatase Shp2.PTPN11 is a member of the protein tyrosine phosphatase ...

, Glycoprotein 130
Glycoprotein 130
Glycoprotein 130 is a transmembrane protein which is the founding member of the class of all cytokine receptors. It forms one subunit of type I cytokine receptors within the IL-6 receptor family...

, Erythropoietin receptor
Erythropoietin receptor
The erythropoietin receptor is a protein that in humans is encoded by the EPOR gene. EpoR is a 59 kDa peptide and is a member of the cytokine receptor family. EpoR pre-exists as dimers...

, Janus kinase 2
Janus kinase 2
Janus kinase 2 is a human protein that has been implicated in signaling by members of the type II cytokine receptor family , the GM-CSF receptor family , the gp130 receptor family , and the single chain receptors...

RAS p21 protein activator 1
RAS p21 protein activator 1 or RasGAP , also known as RASA1, is a 120-kDa cytosolic human protein that provides two principal activities:...

 and Insulin-like growth factor 1 receptor.

Regulation

There is some evidence that the expression of SOCS3 is regulated by the microRNA miR-203.
