CRISPR DNA targeting enzymes and systems

The disclosure describes novel systems, methods, and compositions for the manipulation of nucleic acids in a targeted fashion. The disclosure describes non-naturally occurring, engineered CRISPR systems, components, and methods for targeted modification of a nucleic acid.

CRISPR RNA targeting enzymes and systems and uses thereof

Disclosed here is a method of identifying novel CRISPR effectors, comprising: identifying sequences in a genomic or metagenomic database encoding a CRISPR array; identifying one or more Open Reading Frames (ORFs) in said selected sequences within 10 kb of the CRISPR array; discarding all loci encoding proteins which are assigned to known CRISPR-Cas subtypes and, optionally, all loci encoding a protein of less than 700 amino acids; and identifying putative novel CRISPR effectors, and optionally classifying them based on structure analysis.

Methods for identifying class 2 crispr-cas systems

In one aspect, embodiments disclosed herein are directed to engineered CRISPRCas effector proteins that comprise at least one modification compared to an unmodified CRISPR-Cas effector protein that enhances binding of the of the CRISPR complex to the binding site and/or alters editing preference as compared to wild type. In certain example embodiments, the CRISPR-Cas effector protein is a Type II effector protein. In certain other example embodiments, the Type V effector protein is Cas9 or an orthologs or engineered variant thereof. Example Cas9 proteins suitable for use in the embodiments disclosed herein are discussed in further detail below.

CRISPR enzymes and systems

A system for monitoring pressure within a volume defined by a wall has a housing and a manometer coupled to the housing having fluid therein. The manometer is coupled to the volume and has a fluid level corresponding to a pressure within the volume. A pressure sensor is coupled to the housing and is coupled to volume. The pressure sensor generates a pressure signal corresponding to the pressure within the volume. A controller is coupled to the pressure sensor and is programmed to compare the pressure signal to a threshold and programmed to generate an indicator based on comparing.

The disclosure describes non-naturally occurring, engineered CRISPR systems, components, and methods for targeted modification of nucleic acids such as DNA. Each system includes one or more protein components and one or more nucleic acid components that together target nucleic acids.

CRISPR DNA and RNA targeting enzymes and systems

The disclosure describes novel systems, methods, and compositions for the manipulation of nucleic acids in a targeted fashion. The disclosure describes non-naturally occurring, engineered CRISPR systems, components, and methods for targeted modification of DNA, RNA, and protein substrates. Each system includes one or more protein components and one or more nucleic acid components that together target DNA, RNA, or protein substrates.

CRISPR-associated transposon systems and components

Embodiments disclosed herein provide methods for identifying new CRISPR loci and effectors, as well as different CRISPR loci combinations found in various organisms. Class-II CRISPR systems contain single-gene effectors that have been engineered for transformative biological discovery and biomedical applications. Discovery of additional single-gene or multi-component CRISPR effectors may enhance existing CRISPR applications, such as precision genome engineering. Comprehensive characterization of CRISPR-loci may identify novel functional roles of CRISPR loci enabling new tools for biomedicine and biological discovery. CRISPR loci have enormous feature complexity, but classification of CRISPR loci has been focused on a small fraction of highly abundant features. Increased genome sequencing has enhanced the sampling of this feature complexity.
