<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome. This score <strong>cannot</strong> be used as a measure of the accuracy of the annotation as we cannot define the 'correct annotation' for any given protein.<p><a href='/help/annotation_score' target='_top'>More...</a></p>

Transcription factor required for both mesoderm and endoderm formation in the embryo; signaling determinants and concentration levels may determine which germ layer is formed. Acts together with beta-catenin to activate genes that are responsible for mesoderm induction including wnt-8, eomes t/bra, siamois, mix1 and sox17. Directly binds to promoter DNA. Patterns the mesoderm along the dorsoventral and posterior axis. Activates siamois gene transcription when alone or in combination with beta-catenin, but inhibits siamois transcription in combination with pou5f1.1/oct-25.

Uniformly distributed in stage I oocytes but becomes localized to the vegetal hemisphere by stage II and remains so thereafter throughout oogenesis and the early embryonic cleavage stages. Zygotic expression parallels blastopore formation and shifts from dorsal expression in the marginal zone of late blastula and early gastrula stages to a ventral/lateral expression at the posterior end of later stage embryos. Expression is excluded from the notochord. In tailbud and tadpole stages, expressed exclusively in a subset of posterior Rohon-Beard neurons.4 Publications

Expressed both maternally and zygotically. Maternally expressed from early oogenesis. Zygotic expression occurs from late blastula and reaches maximum levels during gastrulation (stages 10.5-12). Levels decline at the time of blastopore closure (stage 13).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.
