JIL-1 | Chromosomal serine/threonine-protein kinase JIL-1; Phosphorylates 'Ser-10' of histone H3. May regulate gene expression by establishing or maintaining the structure of more open chromatin regions. Also required for normal polytene chromosome structure, for oogenesis and for viability throughout development. Regulates the structure of polytene chromosomes in salivary glands. May phosphorylate 'Ser-1' of histone H2A. (1207 aa) | ||||
nab | NGFI-A-binding protein homolog; Transcriptional regulator that can both act as a coactivator or a corepressor depending on the context. Lacks DNA-binding domains and acts by associating with other transcription factors such as rotund (rn) and squeeze (sqz). Acts as a coactivator of sqz and is required to limit the number of neurons that express the LIM-homeodomain gene apterous and to specify Tv neuronal fate. Acts as corepressor of rn in wing development and is required to limit the expression of wingless (wg) in the wing hinge, where wg plays a mitogenic role. Belongs to the NAB family. (625 aa) |
