CD27 Antibody – Hamster Monoclonal

The protein encoded by this gene is a member of the TNF-receptor superfamily. This receptor is required for generation and long-term maintenance of T cell immunity. It binds to ligand CD70, and plays a key role in regulating B-cell activation and immunoglobulin synthesis. This receptor transduces signals that lead to the activation of NF-kappaB and MAPK8/JNK. Adaptor proteins TRAF2 and TRAF5 have been shown to mediate the signaling process of this receptor. CD27-binding protein (SIVA), a proapoptotic protein, can bind to this receptor and is thought to play an important role in the apoptosis induced by this receptor. [provided by RefSeq, Jul 2008]

Function: Receptor for CD70/CD27L. May play a role in survival of activated T-cells. May play a role in apoptosis through association with SIVA1.

Subunit structure: Homodimer. Interacts with SIVA1 and TRAF2. Ref.8 Ref.9

Subcellular location: Membrane; Single-pass type I membrane protein.

Tissue specificity: Found in most T-lymphocytes.

Post-translational modification: Phosphorylated.O-glycosylated with core 1 or possibly core 8 glycans. Ref.10

Involvement in disease: Lymphoproliferative syndrome 2 (LPFS2) [MIM:615122]: An autosomal recessive immunodeficiency disorder associated with persistent symptomatic EBV viremia, hypogammaglobulinemia, and impaired T cell-dependent B-cell responses and T-cell dysfunction. The phenotype is highly variable, ranging from asymptomatic borderline-low hypogammaglobulinemia, to a full-blown symptomatic systemic inflammatory response with life-threatening EBV-related complications, including hemophagocytic lymphohistiocytosis, a lymphoproliferative disorder, and malignant lymphoma requiring stem cell transplantation.Note: The disease is caused by mutations affecting the gene represented in this entry. Ref.11 Ref.12

Sequence similarities: Contains 3 TNFR-Cys repeats.
