DESCRIPTION
Also known as PTA12_ARATH, PTAC12, HMR, PAP5, TAC12. Involved in plastid gene expression (PubMed:16326926). Required in the nucleus for the initiation of photomorphogenesis mediated by phytochromes (PHYs) (e.g. PHYA and PHYB) by mediating PHYs localization to photobodies, especially in response to red and far-red light, and implicating phytochrome nuclear bodies as sites of proteolysis for PHYs and PIFs proteins (e.g. PIF1 and PIF3). Acts downstream of PHYs and upstream of DET1 (PubMed:20603003, PubMed:22895253). Component of the transcriptionally active chromosome (TAC) complexes (PubMed:21949211, PubMed:22010110). Interacts with PTAC14 and PTAC7 (PubMed:22010110, PubMed:23082802). Binds to photoactivated phytochromes (e.g. PHYA and PHYB) via their photosensory domains; these interactions stimulate its light-mediated accumulation (PubMed:22895253).
