UniProt Contributed Function Data
Chromatin-associated factor that regulates transcription (PubMed:21752937). Regulates Pol I-mediated rRNA biogenesis and, probably, Pol III-mediated transcription (PubMed:29065309). Regulates the localization to the nucleolus of Cdk7, a regulator of the Pol I-elongation factor TFIIH (PubMed:29065309). Acts as regulator of cell proliferation and tissue growth as part of the TORC1 and Myc signaling pathway in response to nutrients (PubMed:29065309). Required in males for both germline stem cell (GSC) maintenance and early stages of germ cell differentiation of germ cell cysts (PubMed:21752937). Not required for female germline stem cell (GSC) maintenance, but necessary to regulate germ cell differentiation and egg chamber development (PubMed:21752937). In female somatic cells, required for follicle stem cell survival and maintenance (PubMed:21752937).

    Additional comments
    "CG6751" may correspond to "Scim24". Sequence analysis off ends of P{SUPor-P} in Scim insertion mutant places "Scim24" near/in "CG6751" or "Taf80".
    Other Comments
    Germ cells can enter differentiation but spermatogenic cysts cannot develop normally in nclb mutant testes.
    nclb is not required for the viability of male germline stem cells, but is required for proper germline stem cell maintenance and for germ cell cysts to complete spermatogenesis once they have initiated differentiation.
    nclb is required in the female germline for germ cell differentiation and egg chamber development, but not for germline stem cell maintenance.
    nclb is not required in differentiated follicle cells, but is required in follicle stem cells for their survival or maintenance.
    The total amount of active transcription is reduced in nclb mutants.
    Origin and Etymology
    Discoverer
    Etymology
    Owing to the defects in fertility and germline development associated with this gene, the authors have named it 'no child left behind'.
