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.
