Annotation score:5 out of 5

<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 activator that plays a role in the regulation of meristematic function in leaves, stems and inflorescences (PubMed:24532604). Transcription activator that plays a regulatory role in grain development (PubMed:26187814, PubMed:27250747, PubMed:27250749, PubMed:26936408, PubMed:27107174). Positively regulates grain size by promoting cell division and expansion, leading to increased grain length and width (PubMed:26187814, PubMed:27250747, PubMed:27250749, PubMed:26936408, PubMed:27107174). Positively regulates the expression of genes promoting cell proliferation (PubMed:26187814, PubMed:26936408). Activates the expression of expansin genes to promote cell expansion and grain size (PubMed:27250747). May promote grain size by activating brassinosteroid responses (PubMed:27250747). Component of a network formed by the microRNA396 (miRNA396), the GRFs and their interacting factors (GIFs) acting in the regulation of meristem function, at least partially through the control of cell proliferation (Probable). Component of the miRNA396c-GRF4-GIF1 regulatory module that plays an important role in grain size determination (Probable) (PubMed:27250747, PubMed:27250749, PubMed:27107174).4 Publications6 Publications

Miscellaneous

Plants over-expressing GRF4 exhibit increased grain length, width and weight (PubMed:27107174). Plants silencing GRF4 exhibit dwarfism, delayed growth and inflorescence formation (PubMed:24532604).2 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. The algorithm is described in the ISO 3309 standard. </p> <p class="publication">Press W.H., Flannery B.P., Teukolsky S.A. and Vetterling W.T.<br /> <strong>Cyclic redundancy and other checksums</strong><br /> <a href="http://www.nrbook.com/b/bookcpdf.php">Numerical recipes in C 2nd ed., pp896-902, Cambridge University Press (1993)</a>)</p> Checksum:i3E71912F42AC1F6E
