General Information

No. Gene Name(s) Paragraph Text
16 HOP3 HOP2B is a homolog of budding yeast HOmologous Pairing 2. It is essential for vegetative growth. HOP2B has a meiosis-specific paralog in Tetrahymena (HOP2, HOP2A, TTHERM_00794620) which is the yeast HOP2 ortholog.
55 HOP3 Hop2 and Mnd1 are meiosis-specific proteins that function in a complex in budding yeast. Their general architecture is strikingly similar, and therefore they are potentially homologous protein families. The Hop2-Mnd1 system seems to have undergone duplication in the evolutionary history of Tetrahymena, because both protein families are represented by two homologs with distinct expression patterns in this species. Just as for HOP2 (meiotic) and HOPP2 (ubiquitous), there is a meiotic (MND1)and a ubiquitously expressed (MNDP1) version, which raises the possibility that a meiotic and a ubiquitous Mnd1p-Hop2p complex exists.
