| Description | The COMPASS complex (complex proteins associated with Set1) is conserved in yeasts and in other eukaryotes up to humans. This entry represents Set1 and its homologues. Set1 is a methyltransferase and the catalytic component of the COMPASS that produces trimethylated histone H3 at Lys(4). The yeast COMPASS (Set1C) complex specifically mono-, di- and trimethylates histone H3 to form H3K4me1/2/3, which subsequently plays a role in telomere length maintenance and transcription elongation regulation [ , , ]. In yeasts, the Set1C complex consists of Set1(2), Bre2(2), Spp1(2), Sdc1(1), Shg1(1), Swd1(1), Swd2(1), and Swd3(1) [, , , ].In animals, SETD1A/B are histone methyltransferases that produce mono-, di-, and trimethylated histone H3 at 'Lys-4. However, if 'Lys-9' residue is already methylated, 'Lys-4' will not be. The 'Lys-4' methylation is a tag for epigenetic transcriptional activation [ , ]. The animal COMPASS complex is composed of at least the catalytic subunit (SETD1A or SETD1B), WDR5, WDR82, RBBP5, ASH2L/ASH2, CXXC1/CFP1, HCFC1 and DPY30 []. ATXR7, the Arabidopsis homologue to Set1, is required for the expression of the flowering repressors FLC and MADS-box genes of the MAF family [, ]. ATXR7 is also involved in the control of seed dormancy and germination []. |
