| + | [[http://www.uniprot.org/uniprot/SMT3_YEAST SMT3_YEAST]] Not known; suppressor of MIF2 mutations. [[http://www.uniprot.org/uniprot/CHP1_SCHPO CHP1_SCHPO]] Component of the kinetochore which plays a role in stabilizing microtubules and so allowing accurate chromosome segregation. Has a role in the RNA interference (RNAi) pathway which is important for heterochromatin formation and accurate chromosome segregation. A member of the RNA-induced transcriptional silencing (RITS) complex which is involved in the biosynthesis of dsRNA from primer siRNAs provided by the RNA-directed RNA polymerase (RDRC) complex.<ref>PMID:9722643</ref> <ref>PMID:10835380</ref> <ref>PMID:15607976</ref> <ref>PMID:14704433</ref> | ||
