MARK4 has an N-terminal kinase domain, a ubiquitin-associated (UBA) domain, and a C-terminal regulatory domain. It forms dimers and localizes to the centrosome.
MARK4 regulates microtubule dynamics by phosphorylating tau and MAP proteins. It is involved in cell polarity, mitosis, and energy metabolism. MARK4 is a downstream effector of LKB1-AMPK signaling.
MARK4 is implicated in neurodegenerative diseases. MARK4 phosphorylates tau at AD-related sites and may promote tau aggregation. Genetic variants in MARK4 are associated with PD risk. MARK4 is upregulated in AD brains.
MARK inhibitors (e.g., Mallotus F) have been investigated. Specific MARK4 inhibitors are in development but face challenges due to homology with other MARK kinases.
