ID BU1B_MOUSE STANDARD; PRT; 1052 AA. AC Q9Z1S0; DT 30-MAY-2000 (Rel. 39, Created) DT 30-MAY-2000 (Rel. 39, Last sequence update) DT 05-JUL-2004 (Rel. 44, Last annotation update) DE Mitotic checkpoint serine/threonine-protein kinase BUB1 beta DE (EC 2.7.1.37) (MAD3/BUB1-related protein kinase) (Mitotic checkpoint DE kinase MAD3L). GN Name=Bub1b; Synonyms=Mad3l; OS Mus musculus (Mouse). OC Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; OC Mammalia; Eutheria; Rodentia; Sciurognathi; Muridae; Murinae; Mus. OX NCBI_TaxID=10090; RN [1] RP SEQUENCE FROM N.A. RC STRAIN=NIH Swiss; TISSUE=Embryo; RX MEDLINE=99107817; PubMed=9889005; RA Davenport J.W., Fernandes E.R., Harris L.D., Neale G.A.M., Goorha R.; RT "The mouse mitotic checkpoint gene bub1b, a novel bub1 family member, RT is expressed in a cell cycle-dependent manner."; RL Genomics 55:113-117(1999). CC -!- FUNCTION: Probable component of the mitotic checkpoint that delays CC anaphase until all chromosomes are properly attached to the CC mitotic spindle. Can interact with BUB3, CENP-F, CENP-E and CC mitosin (By similarity). CC -!- CATALYTIC ACTIVITY: ATP + a protein = ADP + a phosphoprotein. CC -!- SUBUNIT: Interacts with CENP-E, BUB3 and mitosin (By similarity). CC -!- SUBCELLULAR LOCATION: Cytoplasmic in interphase cells. Bound to CC BUB3 or CENP-E, it can be localized to nuclear kinetochores (By CC similarity). CC -!- TISSUE SPECIFICITY: Highly expressed in thymus followed by spleen. CC -!- DOMAIN: CD1 domain directs kinetochore localization and binding to CC BUB3. CC -!- DOMAIN: Cyclin destruction box sequence, which targets protein for CC rapid degradation by ubiquitin-dependent proteolysis during the CC transition from mitosis to interphase. CC -!- SIMILARITY: Belongs to the Ser/Thr protein kinase family. BUB1 CC subfamily. CC -!- SIMILARITY: Contains 1 CD1 domain.
