Ubx | Homeotic protein ultrabithorax; Sequence-specific transcription factor which is part of a developmental regulatory system that provides cells with specific positional identities on the anterior-posterior axis. Binds the consensus region 5'-TTAAT[GT][GA]-3'. This homeotic protein controls development of the cells in the posterior thoracic and first abdominal segments. It activates the synthesis of the decapentaplegic (DPP) growth factor; Belongs to the Antp homeobox family. (389 aa) | ||||
Spc105R | Spc105-related, isoform B; Spc105-related (Spc105R) encodes an essential component of the kinetochore, to which it is recruited by binding to the Mis12 kinetochore complex. The products of Spc105R and Mis12 recruit the Ndc80 complex, which provides the major microtubule binding activity of the kinetochore. (1960 aa) |
