KIF5A, a member of the kinesin superfamily (KIFs), is a neuron-specific motor protein responsible for intracellular cargo transport along microtubules. As part of the kinesin-1 subfamily, it plays a critical role in anterograde movement of organelles, vesicles, and protein complexes in axons, essential for neuronal function and survival. Structurally, KIF5A contains a conserved N-terminal motor domain that binds ATP and microtubules, a central stalk region for dimerization, and a C-terminal tail for cargo recognition. Mutations in the KIF5A gene are linked to neurodegenerative disorders such as amyotrophic lateral sclerosis (ALS) and hereditary spastic paraplegia (HSP), underscoring its biological significance.
Recombinant KIF5A proteins are engineered in vitro using expression systems (e.g., bacterial, insect, or mammalian cells) to study its molecular mechanisms, interactions, and disease-related dysfunction. These purified proteins retain functional domains, enabling researchers to analyze microtubule-binding kinetics, ATPase activity, and cargo-adaptor binding in controlled assays. Tagged versions (e.g., His, GFP) facilitate purification and visualization. Recombinant KIF5A is widely used to model pathogenic mutations, screen therapeutic compounds, and reconstitute transport processes in synthetic systems. Its application enhances understanding of axonal transport defects and aids in developing targeted therapies for neurodegenerative diseases.
