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

Phosphorylates threonine at 'Thr-1823', 'Thr-1833' and 'Thr-2029' in the C-terminal tail region of myosin II heavy chain (mhcA) (By similarity). This phosphorylation is critical in actin-activated ATPase activity of the myosin and regulating the assembly and disassembly of myosin II filament. In vitro, catalytic domain phosphorylates mhcA, myelin basic protein, myosin regulatory light chain, casein and caldesmon. Drives the disassembly of myosin II filaments for efficient cytokinesis and recycling of myosin II that occurs during late cytokinesis. Can be activated in vitro by autophosphorylation.By similarity4 Publications

Null cells exhibit excessive aggregation of myosin II filaments in the cleavage furrows and in the posteriors of the daughter cells once cleavage is complete. The cleavage process is slowed down for cells where the gene is disrupted. Myosin II overassembly increases incrementally in the mutants, with the mhkA, mhkB, mhkC triple mutant showing severe myosin II overassembly and myosin II phosphorylation is highly reduced. Overexpression results in multinucleation of cells.3 Publications

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1.
