背景介绍
Mouse Interleukin-15 Receptor subunit alpha, also known as Il15ra, is a high-affinity Receptor for Interleukin-15. Il15ra associates as a heterotrimer with the IL-2 Receptor beta and gamma subunits (Common gamma chain, or gamma c) to initiate signal transduction. It can signal both in cis and trans where IL15R from one subset of cells presents IL15 to neighboring IL2RG-expressing cells. Il15ra is expressed in special cells including a wide variety of Tand B cells and non-lymphoid cells. Human Il15ra shares 45% amino acid sequence homology with the mouse form of the Receptor. Eight isoforms of IL-15 R alpha mRNA have been identified, resulting from alternative splicing events involving different exons.
