Biological activity: Mouse interleukin-15 receptor subunit alpha, also known as Il15ra, is a high-affinity interleukin-15 receptor. Il15ra binds as a heterotrimer to IL-2 receptor β and γ subunit (ordinary γ chain or γ c) to initiate signal transduction. It can emit both cis and trans signals, in which IL15R from a subset of cells expresses IL15 to neighboring cells that express il2rg. Il15ra is expressed in specialized cells, including a variety of t cells, B cells and non-lymphocyte. The human Il15ra has 45% amino acid sequence homology with the murine form of the receptor. Eight isomers of il-15rα mRNA have been identified, caused by alternative splicing events involving different exons.

Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
