CD27 is a member of the

tumor necrosis factor receptor superfamily.[5] It is currently of interest to immunologists as a co-stimulatory immune checkpoint molecule, and is the target of an anti-cancer drug in clinical trials.[6]

Expression

During mouse embryonic development, specific (medium) expression levels of CD27 (in addition to high

type I transmembrane protein with cysteine-rich domains, but once T cells have become activated, a soluble form of CD27 can be shed.[5][6]

Function

The protein encoded by this gene is a member of the

T cell immunity. It binds to ligand CD70, and plays a key role in regulating B-cell activation and immunoglobulin synthesis.[5]

When CD27 binds CD70, a signaling cascade leads to the differentiation and clonal expansion of T cells.

SIVA), a proapoptotic protein, can bind to this receptor and is thought to play an important role in the apoptosis induced by this receptor.[13]

In murine γδ T cells its expression has been correlated with the secretion of IFNγ.[14]

Clinical significance

As a drug target

Varlilumab is an IgG1 antibody that binds to CD27 and is an experimental cancer treatment.[6] This agonist antibody stimulates CD27 when it binds.[6] The drug is in early clinical trials and appears to stimulate T cells and increase production of cytokines such as interferon-gamma.[6][11]

Interactions

CD27 has been shown to

Mutations

Some mutations can decrease the expression of CD27. Three such mutations, C53Y, C96Y, and R107C, are located in the cysteine-rich domains of CD27.[5]
