Recombinant Human Wnt-16b Protein

描述

Description
The Wnts is a large family of secreted proteins with roles in pattern formation, cell fate decision, axon guidance, and tumor formation. Wnt signaling induces and maintains the transformed phenotype and, in certain embryonic cell lines, supports self-renewal in the absence of significant differentiation. Elevated levels of Wnt proteins are associated with tumorigenesis and are present in numerous human breast cancers. Wnt family members are highly hydrophobic, and possess 22 to 24 conserved cysteines.
Wnt‑16a and Wnt‑16b isoforms in humans differ in the signal sequence and the first two amino acids (aa) of the mature protein. Wnt‑16b is the more conserved isoform and is widely expressed. Wnt‑16 signaling through both canonical and JNK‑mediated (non‑canonical) pathways is reported.
