Protein function
Encodes a subunit of the COP1/SPA E3 ubiquitin-protein ligase complex.
Phenotype
Single mutant: spa2 single mutant does not display any flowering-time phenotype.
[Laubinger et al., 2006] Multiple mutant: spa2;
spa3;
spa4 multiple mutant shows only a minor flowering-time phenotype under SD conditions only. ( Conflicting results about the early- or late-flowering phenotype.)
[Laubinger et al., 2006][Balcerowicz et al., 2011] Function:Involved in suppression of photomorphogenesis in dark-grown seedlings. Probably part of the COP1/SPA E3 ubiquitin-protein ligase complex.
