Found in all the tissues and cell lines examined (PubMed:2261637). Expression not restricted to IL6 responsive cells (PubMed:2261637). Expressed in blood serum (at protein level) (PubMed:24629561).

The protein encoded by this gene is a signal transducer shared by many cytokines, including interleukin 6 (IL6), ciliary neurotrophic factor (CNTF), leukemia inhibitory factor (LIF), and oncostatin M (OSM). This protein functions as a part of the cytokine receptor complex. The activation of this protein is dependent upon the binding of cytokines to their receptors.



Score>80(red) has high confidence and is suggested to be used for WB detection. *The prediction model is mainly based on the alignment of immunogen sequences, the results are for reference only, not as the basis of quality assurance.

Research Backgrounds


Signal-transducing molecule. The receptor systems for IL6, LIF, OSM, CNTF, IL11, CTF1 and BSF3 can utilize IL6ST for initiating signal transmission. Binding of IL6 to IL6R induces IL6ST homodimerization and formation of a high-affinity receptor complex, which activates Janus kinases. That causes phosphorylation of IL6ST tyrosine residues which in turn activates STAT3. Mediates signals which regulate immune response, hematopoiesis, pain control and bone metabolism (By similarity). Has a role in embryonic development (By similarity). Does not bind IL6. Essential for survival of motor and sensory neurons and for differentiation of astrocytes (By similarity). Required for expression of TRPA1 in nociceptive neurons (By similarity). Required for the maintenance of PTH1R expression in the osteoblast lineage and for the stimulation of PTH-induced osteoblast differentiation (By similarity). Required for normal trabecular bone mass and cortical bone composition (By similarity).


Phosphorylation of Ser-782 down-regulates cell surface expression.

Heavily N-glycosylated. Glycosylation is required for protein stability and localization in plasma membrane but not for ligand binding.

Subcellular Location:

Cell membrane>Single-pass type I membrane protein.

Tissue Specificity:

Found in all the tissues and cell lines examined. Expression not restricted to IL6 responsive cells. Expressed in blood serum (at protein level).

Subunit Structure:

Component of a hexamer of two molecules each of IL6, IL6R and IL6ST. Forms heterodimers composed of LIFR and IL6ST (type I OSM receptor) which are activated by LIF and OSM. Also forms heterodimers composed of OSMR and IL6ST (type II receptor) which are activated by OSM but not by LIF. Homodimer. Interacts with HCK. Interacts with INPP5D/SHIP1 (By similarity).

(Microbial infection) The homodimer binds two molecules of herpes virus 8/HHV-8 protein vIL-6.


The WSXWS motif appears to be necessary for proper protein folding and thereby efficient intracellular transport and cell-surface receptor binding.

The box 1 motif is required for JAK interaction and/or activation.

Belongs to the type I cytokine receptor family. Type 2 subfamily.
