Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

Probable plus end-directed motor protein that functions in the NACK-PQR (NPK1-NQK1/MEK1-NRK1) MAP kinase signaling pathway, which is essential for somatic cell cytokinesis, especially for the cell-plate formation and its expansion. Regulates the activity and the localization of NPK1 by association through the non-catalytic region of the kinase.
