Recombinant human serine/threonine-protein kinase BRSK1 (also known as SAD1 or SAD-B) is a key regulator of cell polarity and neuronal development. Belonging to the AMP-activated protein kinase (AMPK) family, BRSK1 contains a conserved N-terminal kinase domain and a C-terminal ubiquitin-associated (UBA) domain that facilitates protein-protein interactions. It is highly expressed in brain tissues, particularly in post-mitotic neurons, where it governs axon-dendrite differentiation, synaptic vesicle localization, and neuronal migration through phosphorylation of substrates like CDC25C and NUAK1.
BRSK1 activity is regulated by upstream kinases such as LKB1/STK11. linking it to energy-sensing pathways and metabolic stress responses. Dysregulation of BRSK1 has been implicated in neurodevelopmental disorders, neurodegenerative diseases, and certain cancers. Recombinant BRSK1 is typically produced using heterologous expression systems (e.g., E. coli or mammalian cells) for structural and functional studies. Its recombinant form enables exploration of substrate specificity, ATP-binding kinetics, and inhibitor screening for therapeutic development. Current research focuses on elucidating its role in autophagy, cell cycle control, and potential cross-talk with Wnt/β-catenin signaling. As a neuron-specific kinase, BRSK1 serves as a valuable target for understanding brain development and designing precision therapies for neurological conditions.
