Appears in the following schemes


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. [Data from UniProt]
