Annotation score:5 out of 5

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

Detected 4 hours after fertilization with maximum levels seen in 6 hours embryos. Expression then declines during gastrulation (6-10 hours), but is still detectable in 24 and 30 hours embryos. The spatial distribution also varies during embryogenesis: at the beginning, expression is localized in deep cells and is absent from the enveloping layer. The pattern then becomes asymmetric, restricting to the forming embryonic shield. By the shield stage, it is highly localized in the axial hypoblast. As gastrulation proceeds, expression continues in the involuting cells, extending from the margin towards the anterior.1 Publication

<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.
