Functional Description ? help Back to Top
Source Description
UniProtInvolved in the regulation of vernalization (By similarity). Binds to DNA in vitro in a non-sequence-specific manner. XLG2 promotes the DNA binding activity of RTV1 specifically to promoter regions of FT and SOC1 in vivo and thus leads to the activation of floral integrator genes. {ECO:0000250, ECO:0000269|PubMed:22232549}.
Function -- GeneRIF ? help Back to Top
  1. a Ca(2+)-dependent G protein, XLG2, promotes RTV1 DNA binding activity for a subset of floral integrator genes and contributes to floral transition.
    [PMID: 22232549]
  2. These findings suggest that RTV1 and ITN1 regulate the subcellular localization of each other.
