Releasing the break on X chromosome inactivation: Rnf12/RLIM targets REX1 for degradation.

Abstract:

:One of the two X chromosomes in cells of female mammals is transcriptionally silenced in a process known as X chromosome inactivation (XCI). Initiation of XCI is regulated by the ubiquitin ligase Rnf12/RLIM, but the mechanisms by which Rnf12/RLIM mediates this process has been a mystery. A recent study by Gontan et al. shows that Rnf12/RLIM targets REX1, an inhibitor of XCI, for proteasomal degradation, providing an answer to this question.

  • Crystal structure and biochemical analyses reveal Beclin 1 as a novel membrane binding protein.

    abstract::The Beclin 1 gene is a haplo-insufficient tumor suppressor and plays an essential role in autophagy. However, the molecular mechanism by which Beclin 1 functions remains largely unknown. Here we report the crystal structure of the evolutionarily conserved domain (ECD) of Beclin 1 at 1.6 Å resolution. Beclin 1 ECD exhi...
