Resistin-Like Molecule- alpha , or RELM- alpha , is a cytokine member to a unique family of Proteins including Relm- beta and Resistin. Relm- alpha and Resistin are secreted by adipocytes, where as Relm- beta is secreted by intestinal epithelial cells. All members of the family share a high conserved C-terminal region with 10 Cysteine residues. Recombinant RELM- alpha is a non-glycosylated Protein, containing 88 amino acids, with a molecular weight of 10 kDa.
