TNFSF4
(Tumor Necrosis Factor (Ligand) Superfamily, Member 4 (TNFSF4))
Tumor necrosis factor ligand superfamily member 4 (TNFSF4) is also known as glycoprotein Gp34, OX40 ligand (OX40L),which belongs to the tumor necrosis factor family. It is expressed on such cells as DC2s (a subtype of dendritic cells) enabling amplification of Th2 cell differentiation.
分子量
42.6 kDa. Due to glycosylation, the protein migrates to 52-56 kDa based on Tris-Bis PAGE result.
