RARRES2, as known as retinoic acid receptor responder protein 2, is a distant member of the Cystatin superfamily. Members of this superfamily contain at least two intra-chain disulfide bonds and an alpha- helical structure over a distance of about 100aa. This protein was found to stimulate chemotaxis of dendritic cells and macrophages to the site of inflammation. Also, it has been implicated in autocrine/paracrine signaling for adipocyte differentiation and also stimulation of lipolysis. Recombinant protein corresponding to aa21-157 from human RARRES2, fused to His-Tag at C-terminal, expressed in insect cell (Baculovirus). Molecular Weight: ~16.9kD (146aa), 18-28kD (SDS-PAGE under reducing conditions.)
