The present invention generally relates to libraries, compositions, methods, applications, kits and screens used in functional genomics that focus on gene function in a cell and that may use vector systems and other aspects related to Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-Cas systems and components thereof. Provided are vectors and vector systems, some of which encode one or more components of a CRISPR complex, as well as methods for the design and use of such vectors. Also provided are methods of directing CRISPR complex formation in eukaryotic cells and methods for utilizing the CRISPR-Cas system.

Functional genomics using CRISPR-Cas systems, compositions, methods, screens and applications thereof

The disclosure includes non-naturally occurring or engineered CRISPR Cas9, each associated with at least one destabilization domain (DD), along with compositions, systems and complexes involving the DD-CRISPR Cas9, nucleic acid molecules and vectors encoding the same, delivery systems involving the same, uses therefor.

CRISPR having or associated with destabilization domains

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

The invention provides for systems, methods, and compositions for altering expression of target gene sequences and related gene products. Provided are structural information on the Cas protein of the CRISPR-Cas system, use of this information in generating modified components of the CRISPR complex, vectors and vector systems which encode one or more components or modified components of a CRISPR complex, as well as methods for the design and use of such vectors and components. Also provided are methods of directing CRISPR complex formation in eukaryotic cells and methods for utilizing the CRISPR-Cas system. In particular the present invention comprehends optimized functional CRISPR-Cas enzyme systems. In particular the present invention comprehends engineered new guide architectures to be used in optimized CRISPR-Cas enzyme systems.

Engineering of systems, methods and optimized guide compositions with new architectures for sequence manipulation

Embodiments of the disclosure include compositions and methods for treating diseases (e.g., brain diseases) using genetic engineered cells. In some cases, the cells are engineered hematopoietic stem cells (HSCs), which are capable of engrafting to a central nervous system and differentiating to progeny cells (e.g., microglial cells).

Microglial progenitors for regeneration of functional microglia in the central nervous system and therapeutics uses thereof

The present invention offers a new approach for highly multiplexed, programmable antiviral therapies that directly target viral RNA, and can be flexibly adapted to target novel viruses or emerging outbreak pathogens. Class 2, type VI CRISPR system-based therapies can be used in combination with existing antiviral compounds for viruses where such compounds exist, either by increasing their efficacy or by preventing the evolution of specific drug resistance mutations. Perhaps most excitingly, if a virus evolves resistance to a specific guide RNA sequence, it is easy to switch to a different guide RNA sequence, or to design a new guide sequence to target the new mutation. Such approaches should prevent the widespread development of resistance to Class 2, type VI CRISPR system-based therapies.
