Supernegatively charged proteins and uses thereof

Abstract

Provided herein are compositions, systems, and methods for delivering an effector protein into a cell. The present disclosure, in some aspects, provide novel proteins delivering an effector protein into a cell. The novel proteins are supernegatively charged proteins derived from highly anionic proteins identified from the proteome (e.g., human proteome). The novel protein tags can be associated (e.g., covalently or nocovalently) with the protein to be delivered to facilitate delivery of the effector protein into a cell.

Dependencies are inferred from the claim text.
