AIF1L, also known as allograft inflammatory factor 1-like, is a cytoplasmic, cytokine-induced, calcium-binding protein first discovered in rat cardiac allografts with chronic rejection. This protein is a marker of human microglia and is expressed by macrophages in injured skeletal muscle and regulates reduced proliferation and differentiation of satellite cells. Recombinant protein corresponding to aa1-150 of human AIFiL, fused to His-tag at N-terminal expressed in E. coli.
