Facts about Serine/threonine-protein kinase TAO2.
Activates the MAPK14/p38 MAPK signaling pathway through the particular activation and phosphorylation of the upstream MAP2K3 and MAP2K6 kinases. Isoform 1, but not isoform 2, plays a role in apoptotic morphological changes, such as cell contraction, membrane blebbing and apoptotic bodies formation.

Ubiquitously expressed, with a higher level of expression in testis and brain.
Cytoplasmic vesicle membrane; Multi-pass membrane protein. Cytoplasm, cytoskeleton. Nucleus. Catalytically active full-length phosphorylated isoform 1 localizes to microtubules in the cytoplasm predominantly on microtubule cables positioned around the nucleus. A C-terminally truncated form of isoform 1 is present in the nucleus; isoform 2 and kinase-defective, as well as full-length isoform 1 are excluded from the nucleus.; [Isoform 2]: Cell projection, dendrite. In dendrites, colocalizes with PCDH8.
