Research Abstract |
We found that cyclin F was covalently conjugated with GdX (GdXylation). Our data suggested that GdXylation of cyclin F regulated its protein stability and cell cycle progression. Although we identified 11 GdX- and 23 RNF (candidate of GdXligase)-binding proteins by biochemical techniques, identification of E1, E2 and E3 enzymes for GdXylation could not be achieved.It was suggested that RNF is functional as a ubiquitinligase in mouse spermatogenesis by analysis of RNF-deficient mice. So we will develop the functional analysis of RNF in future.
