Abstract: Neural kinase (Nuk) encodes a murine receptor-like tyrosine kinase belonging to the Eph/Elk/Eck family. Protein localization studies indicate that during early embryogenesis Nuk is confined to the developing nervous system, where it marks segments along the axis of the neural tube in the hindbrain (rhombomeres r2, r3 and r5) and specific morphological bulges of the midbrain and forebrain. Subcellular localization of Nuk indicates that this receptor is concentrated at sites of cell-cell contact, often involving migrating neuronal cells or their extensions. Most notably, high levels of Nuk protein are found within initial axon outgrowths and associated nerve fibers. The axonal localization of Nuk is transient and is not detected after migrations have ceased, suggesting a role for this tyrosine kinase during the early pathfinding and/or fasciculation stages of axonogenesis. The subcellular localization of Nuk, as well as the presence of fibronectin type III and immunoglobulin-like adhesive domains on the extracellular region, suggest this receptor tyrosine kinase may function to regulate specific cell-cell interactions during early development of the murine nervous system.
