Target Background

Function
Inner nuclear membrane protein. Involved in the attachment of membrane vesicles to chromatin during nuclear assembly, and is probably required for centrosome maturation and cell cycle progression during mitosis. Essential for differentiation of certain tissues and the maintenance of progenitor cell populations. Required for the differentiation and maintenance of male and female germline stem cells (GSCs), as well as the maintenance of somatic cells in the GSC niche. This role is likely to be independent of the BMP (Dpp) pathway that negatively regulates bam transcription during GSC differentiation. During development, plays essential and redundant functions with the other LEM domain proteins; bocks and MAN1. Also has a redundant but important role with bocks during larval development.
Gene References into Functions
  1. Ote is required autonomously for survival of male and female stem cell populations, as well as non-autonomously for maintenance of two somatic niches. Ote loss in ovary causes a decrease in cap cell number and altered signal transduction. Ote mutant males become prematurely sterile as they age. PMID: 27174470
  2. production of Bocks, but not dMAN1, rescued ote-/- sterility, demonstrating that Ote and Bocks are functional homologs PMID: 24700158
  3. We show that the primary defect in ote(-/-) GSCs is a block of differentiation, which ultimately leads to germ cell death. PMID: 23806619
  4. Phosphorylation of Ote at T63 is critical for mitotic progression. PMID: 22751930
  5. Data show that otefin is essential for germline stem cell (GSC) maintenance, is required for the Dpp/BMP signaling pathway to silence bam transcription, and that Ote physically interacts with Medea/Smad4 at the bam silencer element to regulate GSC fate. PMID: 18410727
