**Background of MARK3 Recombinant Protein**
MARK3 (microtubule affinity-regulating kinase 3), also known as C-TAK1. is a member of the serine/threonine protein kinase family. It plays a critical role in regulating microtubule dynamics, cell polarity, and signal transduction pathways. Structurally, MARK3 contains an N-terminal catalytic domain and a C-terminal regulatory region that includes a ubiquitin-associated (UBA) domain and a kinase-associated domain (KA1). These domains mediate interactions with other proteins and modulate its enzymatic activity.
MARK3 is involved in phosphorylating microtubule-associated proteins (MAPs), such as tau, which influences their ability to stabilize microtubules. Dysregulation of MARK3 has been linked to pathological conditions, including neurodegenerative diseases (e.g., Alzheimer’s) and cancer, where aberrant cell division or polarity may contribute to tumor progression. Its role in insulin signaling and energy metabolism via AMPK-related pathways further highlights its multifaceted functions.
Recombinant MARK3 protein is typically produced using expression systems like *E. coli* or mammalian cells, enabling large-scale purification for research applications. The recombinant form retains kinase activity and is used to study enzymatic mechanisms, screen inhibitors, or explore substrate interactions *in vitro*. Researchers employ techniques such as phosphorylation assays, structural studies (e.g., crystallography), or cell-based models to dissect MARK3's biological roles.
The development of MARK3 recombinant protein has advanced drug discovery efforts, particularly in targeting kinase-driven diseases. Its study also contributes to understanding cellular homeostasis, offering insights into therapeutic strategies for conditions marked by cytoskeletal dysfunction or metabolic imbalance.
