E(bx) | Nucleosome-remodeling factor subunit NURF301; Histone-binding component of NURF (nucleosome remodeling factor), a complex which catalyzes ATP-dependent nucleosome sliding and facilitates transcription of chromatin. Specifically recognizes H3 tails trimethylated on 'Lys-4' (H3K4me3), which mark transcription start sites of virtually all active genes. Required for homeotic gene expression, proper larval blood cell development, normal male X chromosome morphology, ecdysteroid signaling and metamorphosis. Belongs to the BPTF family. (2761 aa) | ||||
BubR1 | Bub1-related kinase (BubR1) encodes a motif-rich protein with a C-terminal serine-threonine kinase domain. During prometaphase and metaphase, it plays important roles in spindle assembly checkpoint signalling, stabilization of kinetochore-microtuble attachments and chromosome alignment. It is also essential to maintain sister-chromatid cohesion during meiotic progression and for normal maintenance of Synaptonemal Complex in females. (1460 aa) |
