This document provides methods and materials related to genetic variations of developmental disorders.

For example, this document provides methods for using such genetic variations to assess susceptibility of developing Autism Spectrum Disorder.

The present invention refers to a fusion protein or a protein complex comprising a DNA binding protein (DnaBP), a nucleobase modifying protein (NMP), and a Base Excision Repair associated protein (BERAP. Also, described herein are a method of replacing a cytosine with a guanine on a DNA strand in a cell and a method of treating a subject having or suspected of having a disease or disorder.

The disclosure provides biosynthetic platforms that generate olivetolic acid and its analogues at high titers from microbes, and in cell free systems.

Provided herein are compositions and methods for modulating induction of quorum sensing in bacterial cells. For example, provided herein is a method of inducing method of inducing quorum sensing, where the method includes: culturing a bacterial strain, wherein the bacterial strain comprises a first nucleic acid sequence encoding a first activator polypeptide, wherein expression of the first activator polypeptide produces a quorum sensing molecule precursor; a second nucleic acid sequence encoding a second activator polypeptide, wherein expression of the second activator polypeptide produces a quorum sensing; a third nucleic acid sequence encoding a third activator polypeptide that is capable of activating the quorum sensing system; a fourth nucleic acid sequence encoding a gene of interest, and contacting the bacterial strain with an inducer molecule; and converting the inducer molecule into a quorum sensing molecule, thereby allowing induction of quorum sensing.

The present invention relates to a fusion protein for enhancing expression efficiency of a target protein. More specifically, the present invention relates to a glutamyl-prolyl-tRNA synthetase from human (hEPRS) WHEP domain (including WHEP domains TRS-1, TRS-2, and TRS-3 which locate at middle sites of the EPRS protein, and linkers connecting the three domains therethrough). When used as a fusion protein for expressing a target protein in E. coli, the hEPRS WHEP domain according to the present invention enhanced water solubility of the target protein.

Described in certain exemplary embodiments herein are programmable DNA nuclease systems and/or components thereof that include or are otherwise associated with a ligase. Also described in certain exemplary embodiments herein are method of using the DNA nuclease systems described herein to modify a nucleic acid sequence.

The present disclosure belongs to the field of biomedicine. Specifically, the present disclosure relates to a circular RNA molecule, a cyclization precursor RNA molecule, a recombinant nucleic acid molecule, a recombinant expression vector, a recombinant host cell, a composition and use thereof in targeted degradation of a protein of interest, as well as a method for preventing or treating a disease. The circular RNA molecule has good membrane permeability, is easily delivered into cells, and has high-efficiency in vivo protein targeted degradation activity. The circular RNA molecule of the present disclosure successfully achieves inhibition of tumor growth, which proves the in vivo protein degradation activity of bio-PROTACs for the first time, and provides a positive and effective treatment solution for the treatment of diseases such as tumor.

The present invention relates generally to production methods, enzymes and recombinant yeast strains for the biosynthesis of clinically important prenylated polyketides of the cannabinoid family. Using readily available starting materials, heterologous enzymes are used to direct cannabinoid biosynthesis in yeast.

The present invention relates to a novel peptide or a partial sequence thereof for enhancing expression efficiency of a target protein, and a fusion protein comprising the same. The novel peptide according to the present invention can enhance expression efficiency of a target protein, and furthermore, the peptide can also be applied to a solubility-enhancing fusion protein in order to enhance solubility of the target protein, so that solubility as well as expression efficiency of the target protein is enhanced, which allows such a peptide to be usefully used for production of a recombinant target protein.

The present invention relates generally to the field of recombinant fatty acid synthesis, particularly in transgenic plants. The application describes genes involved in fatty acid synthesis and provides methods and vectors for the manipulation of fatty acid composition of plant oils. In particular, the invention provides constructs for achieving the integration of multiple heterologous genes involved in fatty acid synthesis into the plant genome, such that the resulting plants produce altered levels of polyunsaturated fatty acids. Also described are methods for enhancing the expression of fatty acid biosynthesis enzymes by co-expressing a silencing suppressor within the plant storage organ.
