IL2RA (human)

Overview
IL2RA Receptor for interleukin-2. Non-covalent dimer of an alpha and a beta subunit. IL2R exists in 3 different forms: a high affinity dimer, an intermediate affinity monomer (beta subunit), and a low affinity monomer (alpha subunit). The high and intermediate affinity forms also associate with a gamma subunit. Note: This description may include information from UniProtKB.
Protein type: Membrane protein, integral
Cellular Component: integral to membrane; plasma membrane; external side of plasma membrane
Molecular Function: interleukin-2 receptor activity; drug binding; interleukin-2 binding
Biological Process: regulation of T cell homeostatic proliferation; Notch signaling pathway; apoptosis; negative regulation of immune response; negative regulation of defense response to virus; positive regulation of activated T cell proliferation; cell proliferation; cell surface receptor linked signal transduction; negative regulation of T cell proliferation; inflammatory response to antigenic stimulus; positive regulation of T cell differentiation; negative regulation of inflammatory response; immune response; activated T cell apoptosis
Reference #:  P01589 (UniProtKB)
