Transcriptional activator acting positively in the phytochrome B signaling pathway. Functions redundantly with VOZ1 to promote flowering downstream of phytochrome B (phyB). Down-regulates 'FLOWERING LOCUS C' (FLC) and up-regulates 'FLOWERING LOCUS T' (FT). Binds to the 38-bp cis-acting region of the AVP1 gene. Binds as a dimer to the palindromic sequence 5'-GCGTNNNNNNNACGC-3'. Interacts with phyB in the cytoplasm and is translocated to the nucleus at signal transmission, where it is subjected to degradation in a phytochrome-dependent manner. Homodimer. Interacts with phytochrome B (phyB). Cytoplasmic in darkness, and translocated to the nucleus depending on the light quality mediated by phytochromes. Ubiquitous. Expressed in the vascular bundles and mesophyll cells of various tissues. Expressed in the root, especially in the root tip. Also detected in stamen filaments, stipules and anthers. By far-red light. Down-regulated by far-red light (at protein level). The VOZ region includes a DNA-binding domain and a dimerization domain. Contains an atypical zinc-finger followed by a basic region structurally related to the NAC domain. Phosphorylated. No visible phenotype. Voz1 and voz2 double mutant displays a late flowering phenotype under long-day conditions.
