CENP-A recruiting complex

A protein complex that includes Mis16(Yippee family) and/or Mis18 (WD repeat) subunits that is involved in the deposition of centromere specific (CENP-A containing) nucleosomes at the centromere.

MWP complex

A protein ternary complex that anchors microtubule minus ends to mitotic spindle pole bodies. The founding complex contains a microtubule anchoring protein (Msd1 in fission yeast), A WD-repeat Wdr8 family protein and and a minus end-directed kinesin.

tRNA (m7G46) methyltransferase complex

A protein complex involved in the catalysis of the formation of the modified nucleotide 7-methylguanine (at position 46 in certain tRNAs, such as tRNA(phe) and tRNA(met). In yeast, it is a heterotetramer of two subunits, Trm8 (catalytic) and Trm82 (WD repeat).

WD40-repeat domain binding

Binding to a WD40 repeat domain of a protein. The WD40 repeat is a short structural motif of approximately 40 amino acids, often terminating in a tryptophan-aspartic acid (W-D) dipeptide. Several of these repeats are combined to form a type of protein domain called the WD domain.

Rpd3S complex

A eukaryotically conserved histone deacetylase complex which deacetylates histones across gene coding regions. Composed of a catalytic histone deacetylase subunit, a chromodomain protein, a SIN3 family co-repressor, and a WD repeat protein (Clr6p, Alp13p, Pst2p, and Prw1p respectively in Schizosaccharomyces; Rpd3p, Sin3p, Ume1p, Rco1p and Eaf3 in Saccharomyces; homologs thereof in other species).

Cyc8(Ssn6)-Tup1 general repressor complex

A corepressor complex containing the WD-repeat protein Tup1p (S. cerevisiae) and Tup11/Tup12 (fission yeast) and the TPR repeat protein Cyc8p (S. cerevisiae) ssn6 (fission yeast) that is recruited to target genes by DNA-bound repressor proteins preferentially at regions where histones are deacetylated by the Clr6 class I HDAC, and recruits the SWI/SNF and SAGA complexes to promoters.

Rpd3L complex

A histone deacetylase complex which deacetylates histones preferentially in promoter regions. Composed of a two copies of catalytic histone deacetylase subunit (S. pombe Clr6/ S. cerevisiae Rpd3p), an Sds-3 family protein (S. pombe /S. cerevisiae Sds3(p) ), two copies of SIN3 family co-repressor (S. pombe Pst1/ S. cerevisiae Sin3p, a WD repeat protein/ histone chaperone (S. pombe Prw1/ S. cerevisiae Ume1p), and a zf- PHD finger ( S. pombe Png2/ S. cerevisiae Pho23p), plus 4 additional subunits, and associated factors.
