**Background of Recombinant MAP4 Protein**
Microtubule-associated protein 4 (MAP4) is a ubiquitously expressed protein that stabilizes and regulates microtubule dynamics, playing critical roles in cellular structure maintenance, mitosis, intracellular transport, and signaling. Unlike neuron-specific MAPs (e.g., tau or MAP2), MAP4 is present in most somatic cells, making it a key target for studying microtubule-related mechanisms in non-neuronal contexts. Structurally, MAP4 contains a conserved microtubule-binding domain and multiple phosphorylation sites, allowing it to modulate microtubule stability in response to cellular cues.
Recombinant MAP4 protein is engineered using molecular cloning techniques, often expressed in *E. coli* or mammalian systems to ensure proper post-translational modifications. Its recombinant form enables precise study of MAP4-microtubule interactions, particularly in cancer and neurodegenerative diseases where microtubule dysregulation is implicated. For example, MAP4 phosphorylation during mitosis influences spindle assembly, while its altered expression correlates with chemoresistance in tumors.
In research, recombinant MAP4 serves as a tool to dissect microtubule-associated pathways, screen microtubule-targeting drugs (e.g., taxanes), and model pathological aggregates seen in tauopathies. Its versatility and broad applicability in cell biology and drug development underscore its importance as a reagent for both basic and translational studies.
