Recombinant human DNAI1 protein is a genetically engineered form of the dynein axonemal intermediate chain 1. a critical component of the dynein motor complex in cilia and flagella. DNAI1. located on chromosome 9. plays a pivotal role in the structural organization and functional motility of cilia by facilitating ATP-dependent microtubule sliding. Defects in DNAI1 are linked to primary ciliary dyskinesia (PCD), a rare autosomal recessive disorder characterized by impaired mucociliary clearance, chronic respiratory infections, and laterality defects such as situs inversus.
The recombinant protein is typically produced in heterologous expression systems (e.g., *E. coli* or mammalian cells) to study its molecular interactions, post-translational modifications, and pathogenetic mechanisms in ciliopathies. It serves as a key reagent for functional assays, antibody production, and structural analyses, aiding in the identification of mutation-specific therapies. Research on recombinant DNAI1 has advanced understanding of ciliary beating dynamics and its correlation with respiratory health, reproductive biology, and embryonic development. Its applications extend to disease modeling, drug screening, and validating gene-editing strategies for PCD treatment.
