The maintenance of pluripotency and specification of cellular lineages during embryonic development are controlled by transcriptional regulatory networks, which coordinate specific sets of genes through both activation and repression. The transcriptional repressor RE1-silencing transcription factor (REST) plays important but distinct regulatory roles in(More)
The progression of cell cycle in embryonic cells from oceanic bionts to mammalians is initiated, promoted and terminated under the regulation of cell cycle gene products, named cyclins, and a p34 (cdc 2). Besides, oncogene (proto-oncogene) products such as p53 and pRB also directly regulate the progression of cell cycle. However, the p34 (cdc 2) which(More)
The posttranslational sulfation of tyrosine has been thought to be initiated by the recognition of specific consensus features by the sulfating enzyme tyrosylprotein sulfotransferase (TPST). However, using these recognition features to identify new tyrosine sulfation sites misses recently characterized sites that lack these features. Rigorous analysis of(More)
