Description : (at3g22590 : 186.0) Encodes PLANT HOMOLOGOUS TO PARAFIBROMIN (PHP), a homolog of human Paf1 Complex (Paf1C) subunit Parafibromin. Human Parafibromin assists in mediating output from the Wnt signaling pathway, and dysfunction of the encoding gene HRPT2 conditions specific cancer-related disease phenotypes. PHP resides in a ~670-kDa protein complex in nuclear extracts, and physically interacts with other known Paf1C-related proteins in vivo. Loss of PHP specifically conditioned accelerated phase transition from vegetative growth to flowering and resulted in misregulation of a very limited subset of genes that included the flowering repressor FLOWERING LOCUS C (FLC).; PLANT HOMOLOGOUS TO PARAFIBROMIN (PHP); CONTAINS InterPro DOMAIN/s: RNA polymerase II accessory factor, Cdc73 (InterPro:IPR007852); Has 502 Blast hits to 395 proteins in 198 species: Archae - 0; Bacteria - 0; Metazoa - 257; Fungi - 127; Plants - 42; Viruses - 0; Other Eukaryotes - 76 (source: NCBI BLink). & (reliability: 372.0) & (original description: no original description)
