초록/해제  
요약Cell and gene therapies rely on the expression of proteins with functions distinct from those natively produced by the body, typically using ones from nonhuman organisms. Due to the immunogenicity of such proteins, however, a trend has emerged toward deriving novel protein function from mutated variants of human proteins or fusions of human protein domains. However, these modifications create nonhuman peptides at mutated residues and interdomain junctions, which still pose a risk of immunogenicity that has largely been left unaddressed. In this thesis, I present a modular workflow for the deimmunization of human-derived therapeutic proteins while maintaining their function using existing machine learning-based predictors of protein function and nonhuman peptide immunogenicity. I then demonstrate this workflow's application to various protein types relevant to synthetic biology, including transcriptional activation domains, RNA-binding domains, and DNA-binding domains. In particular, I demonstrate a method for generating zinc finger arrays derived from human proteins to target arbitrary genomic sequences and increase the transcription of endogenous genes. Overall, I propose and explore a method for generating safer and more efficacious therapeutic proteins for cell and gene therapy which can be readily adapted as more effective underlying algorithms are developed.
