**Background of KATNB1 Recombinant Protein**
KATNB1 (Katanin Subunit B1) is a regulatory component of the katanin complex, a microtubule-severing enzyme critical for cellular processes involving microtubule dynamics. The katanin complex, composed of a catalytic subunit (p60. encoded by *KATNA1*) and a regulatory subunit (p80. encoded by *KATNB1*), plays a pivotal role in disassembling microtubules by generating internal breaks, thereby enabling cytoskeletal remodeling during mitosis, meiosis, and neuronal development. KATNB1 stabilizes the complex, recruits it to specific cellular locations (e.g., spindle poles or centrosomes), and regulates p60’s enzymatic activity through phosphorylation-dependent interactions.
Recombinant KATNB1 protein is engineered *in vitro* using expression systems like *E. coli* or mammalian cells, often fused with affinity tags (e.g., His or GST) to facilitate purification. Its production enables functional studies, including mapping protein-protein interactions (e.g., with p60 or tubulin), dissecting microtubule severing mechanisms, and exploring roles in diseases. Dysregulation of KATNB1 is linked to neurodevelopmental disorders, ciliopathies, and cancer, as aberrant microtubule dynamics can impair cell division, migration, or signaling.
Research applications of recombinant KATNB1 include *in vitro* severing assays, structural analysis (e.g., cryo-EM), and screening for therapeutic agents targeting microtubule-associated pathologies. Its study contributes to understanding cellular architecture regulation and disease mechanisms tied to cytoskeletal defects.
