MUC15 is a membrane-bound mucin. The human MUC15 protein contains an extracelluar domain, a small transmembrane domain, and a highly conserved cytoplasmic tail. MUC15 overexpression suppresses trophoblast-like cell invasion[1][2]. Mucin-15/MUC15 Protein, Cynomolgus (HEK293, Fc) is the recombinant cynomolgus-derived Mucin-15/MUC15 protein, expressed by HEK293 , with C-hFc labeled tag.
