A protein interaction map of the mitotic spindle.
The mitotic spindle consists of a complex network of proteins that segregates chromosomes in eukaryotes. To strengthen our understanding of the molecular composition, organization, and regulation of the mitotic spindle, we performed a system-wide two-hybrid screen on 94 proteins implicated in spindle function in Saccharomyces cerevisiae. We report 604 predominantly novel interactions that were ...
متن کاملA specific interaction between the telomeric protein Pin2/TRF1 and the mitotic spindle
Pin2/TRF1 was independently identified as a telomeric DNA binding protein (TRF1) [1] and as a protein (Pin2) that can bind the mitotic kinase NIMA and suppress its ability to induce mitotic catastrophe [2, 3]. Pin2/TRF1 has been shown to bind telomeric DNA as a dimer [3-7] and to negatively regulate telomere length [8-11]. Interestingly, Pin2/TRF1 levels are regulated during the cell cycle, bei...
متن کاملThe mitotic spindle checkpoint
One of the most awe-inspiring demonstrations in biology is a timelapse video of mitosis viewed with high magnification phase contrast or Nomarski DIC microscopy. From initial chaotic movement comes the orderly alignment of chromosomes at the metaphase plate followed by a flawlessly synchronous splitting of the chromosomes and their gliding separation to the two mitotic poles. Enforcing the timi...
متن کاملA requirement for MAP kinase in the assembly and maintenance of the mitotic spindle
Circumstantial evidence has suggested the possibility of microtubule-associated protein (MAP) kinase's involvement in spindle regulation. To test this directly, we asked whether MAP kinase was required for spindle assembly in Xenopus egg extracts. Either the inhibition or the depletion of endogenous p42 MAP kinase resulted in defective spindle structures resembling asters or half-spindles. Like...
متن کاملThe Spindle Protein CHICA Mediates Localization of the Chromokinesin Kid to the Mitotic Spindle
Microtubule-based motor proteins provide essential forces for bipolar organization of spindle microtubules and chromosome movement, prerequisites of chromosome segregation during the cell cycle. Here, we describe the functional characterization of a novel spindle protein, termed "CHICA," that was originally identified in a proteomic survey of the human spindle apparatus [1]. We show that CHICA ...
