Facts about MAP/microtubule affinity-regulating kinase 4.
Serine/threonine-protein kinase (PubMed:15009667, PubMed:14594945, PubMed:23666762, PubMed:23184942).
Phosphorylates the microtubule-associated protein MAPT/TAU (PubMed:14594945, PubMed:23666762).Also phosphorylates the microtubule-associated proteins MAP2 and MAP4 (PubMed:14594945). Involved in regulation of the microtubule network, causing reorganization of microtubules into bundles (PubMed:14594945, PubMed:25123532).

Ubiquitous. Isoform 2 is brain-specific (PubMed:11326310). Expressed at highest levels in brain and testis. Also expressed in heart, lung, liver, muscle, kidney and spleen (PubMed:14594945).

Cytoplasm, cytoskeleton, cilium axoneme. Cytoplasm. Cell projection, dendrite. Localized at the tips of neurite-like processes in differentiated neuroblast cells. Detected in the cytoplasm and neuropil of the hippocampus.
