General annotation (Comments)

Function

Receptor for interferons alpha and beta. Binding to type I IFNs triggers tyrosine phosphorylation of a number of proteins including JAKs, TYK2, STAT proteins and IFNR alpha- and beta-subunits themselves.

Subcellular location

Isoform 1: Membrane; Single-pass type I membrane protein.

Tissue specificity

IFN receptors are present in all tissues and even on the surface of most IFN-resistant cells. Isoform 1, isoform 2 and isoform 3 are expressed in the IFN-alpha sensitive myeloma cell line U266S. Isoform 2 and isoform 3 are expressed in the IFN-alpha resistant myeloma cell line U266R, isoform 1 is not expressed in U266R. Ref.6

Post-translational modification

Phosphorylated on tyrosine residues by TYK2 tyrosine kinase. Ref.7

Sequence similarities

Belongs to the type II cytokine receptor family.

Contains 3 fibronectin type-III domains.

Sequence caution

The sequence AAH02590.1 differs from that shown. Reason: Miscellaneous discrepancy. Contaminating sequence. Potential poly-A sequence.

Alternative products

This entry describes 3 isoforms produced by alternative splicing. [Align] [Select]
Isoform 1 (identifier: P17181-1)

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.
Isoform 2 (identifier: P17181-2)

Also known as: Sol-1; Soluble form 1;

The sequence of this isoform differs from the canonical sequence as follows:
     428-434: KTKPGNT → NISLNSH
     435-557: Missing.
Note: Incomplete sequence.
Isoform 3 (identifier: P17181-3)

Also known as: Sol-2; Soluble form 2;

The sequence of this isoform differs from the canonical sequence as follows:
     414-421: Missing.
     428-480: Missing.
Note: Incomplete sequence.
