Title	Time-resolved proteomic analysis in zebrafish larvae using bioorthogonal noncanonical amino acid tagging (BONCAT)
Description	Protein synthesis underpins many biological processes, yet tracking time-dependent proteomic changes remains challenging. Bioorthogonal noncanonical amino acid tagging (BONCAT) offers a targeted approach for labeling and identifying newly synthesized proteins within defined time windows of interest. Here, we present the first such application of BONCAT in larval zebrafish, a model organism that has seen widespread use because of its genetic tractability and utility in developmental biology and neuroscience. We successfully enriched, using click chemistry, and identified, via mass spectrometry, azidohomoalanine (AHA)-labeled proteins after labeling durations as short as 12 hours. Proteomic analysis of BONCAT-enriched proteins demonstrated significant signal above background compared to unlabeled controls after both 48 h and 12 h of labeling. As a proof of concept, we investigated proteomic changes in response to heat shock in zebrafish larvae. BONCAT analysis revealed the upregulation of heat shock-induced proteins with greater sensitivity than whole lysate proteomics. Gene set enrichment analysis confirmed that known heat shock response proteins were significantly enriched in the BONCAT dataset but not in the whole lysate dataset, highlighting the ability of BONCAT to detect transient molecular responses otherwise masked in conventional whole lysate approaches. Beyond the expected changes in synthesis of heat shock proteins, BONCAT identified differentially expressed proteins implicated in stress responses, lipid metabolism, and neural regulation, offering insights into the zebrafish heat shock response. These findings establish BONCAT as a powerful tool for time-resolved proteomic analysis in zebrafish. Its ability to enhance signal specificity and resolve protein dynamics opens new avenues for studying molecular underpinnings of behavior, stress, and development in this versatile model organism.
