Publication number: 20240124860Abstract: 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.Type: ApplicationFiled: October 17, 2023Publication date: April 18, 2024Inventors: Feng Zhang, David Arthur Scott, Winston Xia Yan, Sourav Choudhury, Matthias Heidenreich

Patent number: 11922806Abstract: An automobile vehicle continuous validation system includes a backend collecting data from a vehicle fleet and wirelessly communicating with the vehicle fleet. The backend is in wireless communication with at least one client. A vehicle module is provided on-board individual ones of multiple automobile vehicles of the vehicle fleet and performing an on-board vehicle validation analysis. A fleet-based validation module provided either at the backend or cloud based manages data defining a configuration of and a capability of the multiple automobile vehicles of the vehicle fleet. A validation manager generates validation tasks based on a user's definition or a desired production of the validation tasks of the validation analysis and a fleet vehicle availability. A client-side module remote from the multiple automobile vehicles of the vehicle fleet has interface items applied by the at least one client seeking to perform the validation analysis.Type: GrantFiled: February 24, 2022Date of Patent: March 5, 2024Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Shige Wang, Wei Tong, Shuqing Zeng, Xiaofeng Frank Song, Sourav Dey, Praveen Choudhury

Publication number: 20240018552Abstract: Embodiments disclosed herein are directed to engineered CRISPR-Cas effector proteins that comprise at least one modification compared to an unmodified CRISPR-Cas effector protein that enhances binding 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 V effector protein. In certain other example embodiments, the Type V effector protein is Cpf1. Embodiments disclosed herein are directed to viral vectors for delivery of CRISPR-Cas effector proteins, including Cpf1. In certain example embodiments, the vectors are designed so as to allow packaging of the CRISPR-Cas effector protein within a single vector. There is also an increased interest in the design of compact promoters for packing and thus expressing larger transgenes for targeted delivery and tissue-specificity.Type: ApplicationFiled: June 30, 2023Publication date: January 18, 2024Inventors: Feng Zhang, David Arthur Scott, Winston Xia Yan, Sourav Choudhury, Mattias Heidenreich
