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>
-Experimental evidence at protein leveli <p>This indicates the type of evidence that supports the existence of the protein. Note that the 'protein existence' evidence does not give information on the accuracy or correctness of the sequence(s) displayed.<p><a href='/help/protein_existence' target='_top'>More...</a></p>

<p>This section provides any useful information about the protein, mostly biological knowledge.<p><a href='/help/function_section' target='_top'>More...</a></p>Functioni

Probable transcriptional regulator considered as cadastral protein that acts indirectly to prevent the B class homeotic proteins APETALA3 and perhaps PISTILLATA from acting in the gynoecial whorl. Principal function is to balance cell proliferation in the third and fourth whorls of developing flowers thereby maintaining the boundary between stamens and carpels. May fulfill this role by repressing genes implicated in cell division. Plays equally a role in the determinacy of the floral meristem. Is also required for normal ovule development.

5 Publications

Miscellaneous

Mutations in SUP cause the ectopic expression of APETALA3 leading to the development of extra stamens at the expense of the central carpels of the flower.

<p>This subsection of the 'Expression' section reports the experimentally proven effects of inducers and repressors (usually chemical compounds or environmental factors) on the level of protein (or mRNA) expression (up-regulation, down-regulation, constitutive expression).<p><a href='/help/induction' target='_top'>More...</a></p>Inductioni

Repressed by KRYPTONITE/SUVH4, member of the histone H3-K9 methyltransferase family that contributes with other factors to the CpNpG methylation of the SUP gene resulting in its silencing. The alternative epigenetic states of the SUPERMAN locus have been called Clark Kent alleles. Positively regulated at an early stage of development by LEAFY and by B class homeotic proteins APETALA3 and PISTILLATA. Later expression is maintained by both the B class homeotic proteins and the C class homeotic protein AGAMOUS. These two steps of regulation require the intervention of additional factors.1 Publication

Contains two overlapping leucine-zipper-like motifs at the C-terminal region, which might serve as a site for protein-protein interaction. In this domain, a slightly degenerated ERF-associated amphiphilic repression (EAR) motif seems to be involved in the activity of transcriptional repression.
