Interleukin-3 receptor

The Interleukin-3 receptor (pronunciation: /ˌɪntərˈluːkɪn ˈθriː rɪˈsɛptər/) is a type of protein that in humans is encoded by the IL3RA gene.

Etymology

The term "Interleukin-3 receptor" is derived from the words "interleukin", which is a type of cytokine that acts as a cell messenger, and "receptor", which refers to a protein molecule that receives chemical signals from outside a cell. The number "3" indicates that it is the third identified member of the interleukin family.

Function

The Interleukin-3 receptor is a complex of two subunits, the alpha (IL3RA) and the beta (IL3RB) subunit, which are associated with the function of the immune system. The receptor is found on the surface of various hematopoietic cells, where it binds to Interleukin-3 to regulate cell growth and differentiation.
