MAP7 is a microtubule-stabilizing protein that functions as a critical regulator of cytoskeletal dynamics and cargo transport. Structurally, MAP7 contains a microtubule-binding domain that binds along the microtubule lattice through interactions extending beyond single tubulin dimers 1. MAP7 promotes tubulin posttranslational modifications, specifically enhancing acetylation while inhibiting detyrosination, thereby modulating the "tubulin code" 2. The protein functions as a microtubule-tethered kinesin-1 activator, with its projection domain tethering kinesin-1 to microtubules while its binding domain competitively regulates motor processivity in a biphasic manner 34. MAP7 participates in cellular adaptation to osmotic stress through coordinated remodeling of microtubule architecture and intracellular transport 2. Additionally, MAP7 forms a feedback loop with Disheveled to facilitate Wnt5a signaling and microtubule remodeling during cell migration and polarity formation 5. Clinically, MAP7 is upregulated in cervical and breast cancers, where it promotes cancer cell migration, invasion, and proliferation through autophagy and NF-κB pathway modulation 678. Importantly, elevated MAP7 reduces paclitaxel sensitivity in breast cancer cells, suggesting therapeutic relevance 7.
