Control of the migratory pathway of facial branchiomotor neurones.
TLDR
It is shown that during their migration, fbm neurones regulate the expression of genes encoding the cell membrane proteins TAG-1, Ret and cadherin 8, and that Ebf1 is involved in the control of these responses.
Histone H2A.Z and homologues of components of the SWR1 complex are required to control immunity in Arabidopsis.
TLDR
The results support the existence in Arabidopsis of an SWR1-like chromatin remodelling complex that is functionally related to that described in yeast and human, and attribute to this complex a role in maintaining a repressive state of the SAR response.
Ebf gene function is required for coupling neuronal differentiation and cell cycle exit
TLDR
Ebf genes appear to be master controllers of neuronal differentiation and migration, coupling them to cell cycle exit and earlier steps of neurogenesis and gain-of-function data raise the possibility that, in addition to these general roles, Ebf genes may be involved in neuronal subtype specification in particular regions of the CNS.
NtcA represses transcription of gifA and gifB, genes that encode inhibitors of glutamine synthetase type I from Synechocystis sp. PCC 6803
TLDR
The results demonstrate that NtcA plays a central role in GS regulation in cyanobacteria, stimulating transcription of the glnA gene (GS structural gene) and suppressing transcription ofThe GS inactivating factor genes gifA and gifB.
The chromatin remodeling factor CHD8 interacts with elongating RNA polymerase II and controls expression of the cyclin E2 gene
TLDR
A transcriptomic analysis of CHD8-depleted cells found that it controls the expression of cyclin E2 (CCNE2) and thymidylate synthetase (TYMS), two genes expressed in the G1/S transition of the cell cycle, and shows that CHd8 associates with the elongating form of RNAPII, which is phosphorylated in its carboxy-terminal domain.
SUMO association with repressor complexes, emerging routes for transcriptional control.
TLDR
The analysis of the available data uncovers the importance not only of the covalent attachment of SUMO to proteins, but also of the presence in many proteins ofsumO interacting motifs (SIMs) that mediate non-covalent association with SUMO.
A two‐component signal transduction system involved in nickel sensing in the cyanobacterium Synechocystis sp. PCC 6803
TLDR
It is demonstrated that rppA and rppB control the Ni2+‐dependent induction of the nrsBACD operon and are involved in Ni2+, a two‐component signal transduction system involved in redox sensing.
The PHD Domain of Plant PIAS Proteins Mediates Sumoylation of Bromodomain GTE Proteins*
TLDR
A model of interactions is proposed to explain AtSIZ1-mediated sumoylation ofGTE3 and ligase function of the PHD domain, being partially and absolutely required for AtSCE1 and GTE3 sumoylated, respectively.
A Gene Cluster Involved in Metal Homeostasis in the Cyanobacterium Synechocystis sp. Strain PCC 6803
TLDR
The data suggest that this region of the Synechocystis sp.
Purification and characterization of a new type of glutamine synthetase from cyanobacteria.
TLDR
Levels of GSIII protein increased under nitrogen deficiency and polyclonal antibodies specific for GSIII cross-react with GSIII from other cyanobacteria, suggesting that GSIII is specifically required under conditions of nitrogen starvation.
