Background: TRAIL R4/TNFRSF10D
TRAIL-R4, also known as TRAIL-R4 alpha, Decoy Receptor 2 (DcR2) and TNFRSF10D,
is a 39-48 kDa member of the TNFR Superfamily of proteins. Mature TRAIL-R4/DcR2 is a type I
transmembrane protein 331 amino acids (aa) in length. It contains a 156 aa extracellular domain
(ECD) (aa 56-211), and a 154 aa cytoplasmic region that contains a truncated
death domain. The presence of this
truncation is not believed to allow for a positive signal for the initiation of
apoptosis. This has led to its description
as a "decoy receptor", suggesting that its function is to simply sequester and decrease
the amount of TRAIL available for binding to the two apoptosis-inducing TRAIL
receptors, DR4 and DR5. At this time,
this view would appear to be unlikely, as it now seems that DcR2 actually
complexes with DR5/TRAIL-R2, blocking the activation of Caspase-8, a first step
in the initiation of apoptosis. In
addition, in a ligand-dependent manner, the presence of DcR2 has also been
associated with the increased survival of select leukocytes. Notably, an isoform variant for TRAIL-R4
(called TRAIL-R4 beta ) has been reported that shows an absence of aa 87-124, a
deletion that would render it incapable of binding to TRAIL. Cells reported to express TRAIL-R4 are
varied, and include eosinophils, NKT cells, CD8+ (but not CD4+) T cells, colonic
columnar epithelium, neutrophils, endometrial columnar epithelium, testicular
spermatids and testosterone-secreting Leydig cells, and multiple tumor cell
types. A rodent counterpart to TRAIL-R4
has not been reported.
