NAA38 (N-Alpha-Acetyltransferase 38, NatC Catalytic Subunit): NAA38 is a component of the N-terminal acetyltransferase complex responsible for catalyzing the transfer of acetyl groups to the N-terminus of proteins. This modification influences protein stability, localization, and function. Although the precise biological roles and substrate specificity of NAA38 are not yet fully understood, N-terminal acetylation is a common and important post-translational modification. Studying NAA38 and similar enzymes helps reveal regulatory mechanisms of protein function and the impact of protein acetylation on cellular processes and disease.
