The fission yeast Mcs6-Mcs2-Pmh1 complex (homologous to metazoan Cdk7-cyclin HMat1) performs dual functions: in cell cycle control, as a CDK-activating kinase; and in transcription by RNA polymerase (Pol) II, as part of TFIIH. It is unknown whether that linkage serves to coordinate gene expression w...
ORGANISM(S): Schizosaccharomyces pombe 
During S-phase of the eukaryotic cell cycle, controls exist to ensure that replication origins fire only once and become inactivated after traverse of a replication fork. Failure of these controls results in local amplification of the genome which can lead to gene copy increases important for both ...

iPSC-derived microglia export cholesterol to neuronal cells in human brain organoids and promote their maturation
ORGANISM(S): Homo Sapiens (human) 
To achieve faithful replication of the genome once in each cell cycle, re-initiation of S-phase is prevented in G2 and origins are restricted from re-firing within S-phase. We have investigated the block to re-replication during G2 in fission yeast. The DNA synthesis that occurs when G2/M cyclin d...
