IDBG-21516 (IL6ST)

Protein Structure

UniProt Annotation

Function

Signal-transducing molecule. The receptor systems for IL6, LIF, OSM, CNTF, IL11, CTF1 and BSF3 can utilize gp130 for initiating signal transmission. Binds to IL6/IL6R (alpha chain) complex, resulting in the formation of high-affinity IL6 binding sites, and transduces the signal. Does not bind IL6. May have a role in embryonic development (By similarity). The type I OSM receptor is capable of transducing OSM-specific signaling events. {ECO:0000250}.

Subcellular Localization

Isoform 1: Cell membrane; Single-pass type I membrane protein.Isoform 2: Secreted.

Disease Associations

Tissue Specificity

Found in all the tissues and cell lines examined. Expression not restricted to IL6 responsive cells.
