The human ZDHHC19 protein, a member of the DHHC family of palmitoyltransferases, is characterized by a conserved Asp-His-His-Cys (DHHC) motif critical for catalyzing protein S-palmitoylation—a reversible post-translational modification regulating membrane trafficking, stability, and protein-protein interactions. Localized predominantly in the Golgi apparatus and endoplasmic reticulum, ZDHHC19 mediates substrate-specific palmitoylation, influencing cellular processes like signal transduction, organelle dynamics, and neuronal function. Dysregulation of palmitoylation is linked to neurological disorders, cancers, and metabolic diseases, though ZDHHC19's exact pathophysiological roles remain under investigation.
Recombinant ZDHHC19. generated via heterologous expression systems (e.g., E. coli, mammalian cells), retains enzymatic activity for functional studies. Its recombinant form enables structural analysis (e.g., crystallography, cryo-EM) and high-throughput screening to identify substrates or modulators. Recent studies suggest ZDHHC19 may interact with oncogenic or neurosignaling proteins, highlighting therapeutic potential. However, challenges persist in elucidating substrate specificity and regulatory mechanisms due to overlapping roles within the DHHC family. Current research prioritizes mapping its interactome and validating disease associations, positioning ZDHHC19 as a target for precision medicine strategies.
