General annotation (Comments)

Function

This is a receptor for interleukin-21.

Subunit structure

Heterodimer with the common gamma chain. Associates with JAK1.

Subcellular location

Membrane; Single-pass type I membrane protein.

Tissue specificity

Selectively expressed in lymphoid tissues. Most highly expressed in thymus and spleen.

Domain

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.

Sequence similarities

Belongs to the type I cytokine receptor family. Type 4 subfamily.

Contains 1 fibronectin type-III domain.
