    摘要: Described herein are non-naturally occurring neomycin phosphotransferase (NPT) proteins and nucleic acid sequences encoding such NPT proteins. In a specific embodiment, the non-naturally occurring NPT proteins have reduced activity relative to wild-type NPT. The non-naturally occurring NPT proteins provided herein are useful as a selectable marker for screening transformed or transfected cells. Also provided herein are vectors and kits comprising a nucleic acid sequence encoding a non-naturally occurring NPT protein, and methods of producing cells expressing the non-naturally occurring NPT protein and a protein of interest or a non-coding RNA sequence of interest.
