PPM2 Ppm2p

The protein encoded by this intronless gene belongs to the highly variable methyltransferase superfamily. This gene is the inferred homolog of the Saccharomyces cerevisiae carboxymethyltransferase gene PPM2 that is essential for the synthesis of the hypermodified guanosine Wybutosine (yW).

Ancestral and more recently acquired syntenic relationships of MADS-box genes uncovered by the Physcomitrella patens pseudochromosomal genome assembly.
Ashton et al., Regina, Canada. In Plant Cell Rep, Dec 2015
Furthermore, this early segmental duplication spawned two chromosomal lineages: one with a MIKC (C) gene, belonging to the PPM2 clade, in close proximity to one or a pair of MIKC* genes and another with a MIKC (C) gene, belonging to the PpMADS-S clade, characterised by greater separation from syntenic MIKC* genes.
KR-POK interacts with p53 and represses its ability to activate transcription of p21WAF1/CDKN1A.
Hur et al., Seoul, South Korea. In Cancer Res, 2012
Kr-pok interacted directly with the DNA binding and oligomerization domains of p53. This interaction was essential for Kr-pok to bind the distal promoter region of the CDKN1A gene, p21WAF1, and to inhibit p53-mediated transcriptional activation of CDKN1A.

Two ancient classes of MIKC-type MADS-box genes are present in the moss Physcomitrella patens.
Theissen et al., Köln, Germany. In Mol Biol Evol, 2002
Phylogeny reconstructions and comparison of exon-intron structures revealed that the genes described here represent two different classes of homologous, yet distinct, MIKC-type MADS-box genes, termed MIKC(c)-type genes-"(c)" stands for "classic"-(PPM1, PPM2, PpMADS1) and MIKC(*)-type genes (PPM3, PPM4, PpMADS2, PpMADS3).
