**Background of TASP1 Recombinant Protein**
TASP1 (threonine aspartase 1), also known as taspase-1. is a proteolytic enzyme encoded by the *TASP1* gene in humans. It belongs to the N-terminal nucleophile (Ntn) hydrolase family and plays a critical role in cleaving specific peptide bonds within precursor proteins to generate functional fragments. TASP1 is evolutionarily conserved and is essential for normal embryonic development, as demonstrated by studies in knockout models showing embryonic lethality due to defects in cell proliferation and differentiation.
A key function of TASP1 is its involvement in processing mixed-lineage leukemia (MLL) proteins, which regulate *HOX* gene expression and hematopoiesis. By cleaving MLL, TASP1 ensures proper epigenetic regulation of target genes, impacting cell fate decisions and tissue development. Dysregulation of TASP1 activity has been linked to malignancies, including leukemia and solid tumors, where aberrant MLL cleavage contributes to oncogenic transformation.
Recombinant TASP1 protein is produced using heterologous expression systems (e.g., *E. coli* or mammalian cells) to study its enzymatic activity, substrate specificity, and interactions. Structural studies reveal that TASP1 functions as a dimer, with its active site utilizing a threonine residue for catalysis. Researchers employ recombinant TASP1 to investigate its role in cancer biology, developmental disorders, and epigenetic regulation. Inhibitors targeting TASP1 are also under exploration for therapeutic applications.
Beyond oncology, TASP1 is implicated in neuronal development and neurodegenerative diseases, with studies suggesting its involvement in processing proteins like amyloid precursor protein (APP). However, its full physiological and pathological scope remains an active area of research. The availability of recombinant TASP1 facilitates mechanistic studies and drug discovery, offering potential insights into novel treatment strategies for diseases linked to proteolytic dysregulation.
