**Background of DUSP23 Recombinant Protein**
Dual-specificity phosphatase 23 (DUSP23), also known as VHZ or LDP-3. belongs to the dual-specificity phosphatase (DSP) family, which regulates cellular signaling by dephosphorylating both tyrosine and serine/threonine residues on target proteins. Unlike classical DSPs that primarily modulate mitogen-activated protein kinases (MAPKs), DUSP23 exhibits a unique substrate preference and structural features. It contains a conserved catalytic domain but lacks the N-terminal MAPK-binding motif, suggesting divergent regulatory roles.
DUSP23 is implicated in critical cellular processes, including cell cycle progression, DNA damage response, and apoptosis. Studies highlight its involvement in oxidative stress pathways, where it interacts with redox-sensitive proteins to maintain cellular homeostasis. Additionally, DUSP23 overexpression has been observed in certain cancers, such as hepatocellular carcinoma and melanoma, where it may promote tumor growth by suppressing pro-apoptotic signaling or enhancing oncogenic kinase activity.
Recombinant DUSP23 protein is engineered for in vitro studies to elucidate its biochemical properties, enzymatic activity, and interactions. Produced using expression systems like *E. coli* or mammalian cells, it retains phosphatase activity and is utilized in enzymatic assays, structural studies, and inhibitor screening. Its recombinant form also aids in exploring therapeutic potential, as targeting DUSP23 could offer strategies for cancer treatment or managing oxidative stress-related disorders.
Despite progress, DUSP23's precise mechanisms and physiological contexts remain partially understood, necessitating further research to clarify its role in health and disease.
