ncbi summary :
The interleukin 2 receptor, which is involved in T cell-mediated immune responses, is present in 3 forms with respect to ability to bind interleukin 2. The low affinity form is a monomer of the alpha subunit and is not involved in signal transduction. The intermediate affinity form consists of an alpha/beta subunit heterodimer, while the high affinity form consists of an alpha/beta/gamma subunit heterotrimer. Both the intermediate and high affinity forms of the receptor are involved in receptor-mediated endocytosis and transduction of mitogenic signals from interleukin 2. The protein encoded by this gene represents the beta subunit and is a type I membrane protein. [provided by RefSeq, Jul 2008]
uniprot summary :
IL2RB: Receptor for interleukin-2. This beta subunit is involved in receptor mediated endocytosis and transduces the mitogenic signals of IL2. 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. Interacts with SHB upon interleukin stimulation. Interacts with HTLV-1 accessory protein p12I. Belongs to the type I cytokine receptor family. Type 4 subfamily. Protein type: Receptor, cytokine; Membrane protein, integral. Chromosomal Location of Human Ortholog: 22q13.1. Cellular Component: membrane; integral to plasma membrane; plasma membrane; external side of plasma membrane. Molecular Function: interleukin-2 receptor activity; interleukin-2 binding. Biological Process: viral reproduction; cytokine and chemokine mediated signaling pathway; protein complex assembly; signal transduction; negative regulation of apoptosis
