SSA/Ro52 autoantigen interacts with Dcp2 to enhance its decapping activity.

Abstract:

:We identified human decapping enzyme 2 (hDCP2) as a binding protein with Ro52, being colocalized in processing bodies (p-bodies). We also showed that the N-terminus and C-terminus of Ro52 bound to hDCP2. Moreover, Ro52 enhanced decapping activity of hDCP2 in a dose-dependent manner. Our data support the novel notion of the association between Ro52 with hDCP2 protein in cytoplasmic p-bodies, playing a role in mRNA metabolism in response to cellular stimulation.

  • Adipocyte-derived microvesicles contain RNA that is transported into macrophages and might be secreted into blood circulation.

    abstract::We have recently found that 3T3-L1 adipocytes secrete microvesicles, known as adipocyte-derived microvesicles (ADMs), with angiogenic activity. In this study, we found that ADMs contain RNA without typical 28S and 18S ribosomal RNA inside the vesicles. Microarray analysis revealed that ADMs contain approximately 7000 ...
