CD134 (OX-40 receptor)is a 50 kd type I membrane protein, expressed on activated T cells.It binds to the OX-40 ligand (CD252) to provide a co-stimulatory signal that is independent of CD28.It is reported to block binding of CD134 and CD252.

Other Names: OX-40 receptor , TNFRSF4, ACT35, OX40
Structure: 50 kd type I integral membrane protein, member of NGFR/TNFR superfamily.
Distribution: Expressed mainly on activated CD4+ and CD8+ T cells.
Function: Binds to the OX-40 ligand (CD252) to provide a co-stimulatory signal for T cells.
Ligand Receptor: CD252 (OX-40 ligand)
