Histone Demethylation Mediated By The Nuclear Amine Oxidase Homolog LSD1
LSD1, a homolog of nuclear amine oxidases, functions as a histone demethylase and transcriptional co-repressor. LSD1 specifically demethylates histone H3 lysine 4, which is linked to active transcription. Lysine demethylation occurs via an oxidation reaction that generates formaldehyde. Importantly, RNAi inhibition of LSD1 causes an increase in H3 lysine 4 methylation and concomitant de-repression of target genes, suggesting that LSD1 represses transcription via histone demethylation. The results thus identify a histone demethylase conserved from S. pombe to human and reveal dynamic regulation of histone methylation by both histone methylases and demethylases.

Immunogenic bacterial vesicles with outer membrane proteins
ActiveUS20100015212A1Good curative effectHighly effective in raisingAntibacterial agentsBiocideLytic transglycosylase activityImmunogenicity
Knockout of the meningococcal mltA homolog gives bacteria that spontaneously release vesicles that are rich in immunogenic outer membrane proteins and that can elicit cross-protective antibody responses with higher bactericidal titres than OMVs prepared by normal production processes. Thus the invention provides a bacterium having a knockout mutation of its mltA gene. The invention also provides a bacterium, wherein the bacterium: (i) has a cell wall that includes peptidoglycan; and (ii) does not express a protein having the lytic transglycosylase activity of MltA protein.

PendingCN114019169AQuick checkNo action requiredBacteriaMicroorganism based processesProtein targetFree protein
The invention discloses a method for quantitatively detecting the target protein yield of a cell-free protein synthesis system and screening zymoprotein with high catalytic activity. According to the method for quantitatively detecting the yield of the target protein in the CFPS system, the expression quantity of the target protein in the CFPS system can be rapidly analyzed by segmenting the intensity value of fluorescence emitted by spontaneous binding of fluorescent protein, and rapid detection of the expression quantity of the target protein in the CFPS system is facilitated; meanwhile, based on the method, the enzyme homologues with high catalytic activity can be quickly screened by calculating the ratio of the quantity of products obtained by catalysis of each enzyme protein to the fluorescence intensity value after spontaneous binding of segmented fluorescent protein, and a conventional large intestine transformation-expression-purification process is not needed, so that the time and the material cost are greatly saved, the screening speed is increased, and moreover, the screening leakage risk of the high-catalytic-activity protein caused by too low protein expression quantity is avoided, and rapid and accurate screening of the high-catalytic-activity zymoprotein is facilitated.

Potential Prognostic Markers and Therapeutic Targets for Neurological Disorders
We recently found that Satb1 is expressed highly by mature neurons in specific regions of the postnatal brain. Satb2, a homolog of Satb1, is expressed at low levels in the postnatal brain. Neurons respond to external stimuli and rapidly and dynamically change their expression. Satb1 has been found to directly regulate a set of genes in the postnatal brain, presumably playing a crucial role as a ‘genome organizer’ for brain function and behaviors. Satb2 may also have a similar function, even though it is expressed at low levels in the postnatal brain. The present invention describes compositions, reagents and tools using wild type and variant SATB1 and SATB2 genes and proteins for use in diagnosis, prognosis and therapeutics in neurological dysfunction and psychiatric disorders.
