BIM1 encodes a microtubule-binding protein in yeast.
A previously uncharacterized yeast gene (YER016w) that we have named BIM1 (binding to microtubules) was obtained from a two-hybrid screen of a yeast cDNA library using as bait the entire coding sequence of TUB1 (encoding alpha-tubulin). Deletion of BIM1 results in a strong bilateral karyogamy defect, hypersensitivity to benomyl, and aberrant spindle behavior, all phenotypes associated with muta...
متن کاملDynamin: a microtubule-associated GTP-binding protein.
We recently identified dynamin as a third nucleotide-sensitive microtubule-associated protein in brain tissue, in addition to kinesin and cytoplasmic dynein. Molecular cloning analysis has revealed that dynamin contains the three consensus elements characteristic of GTP-binding proteins, and biochemical results support a role for GTP in dynamin function. Dynamin is also homologous to the Mx pro...
متن کاملStu2p: A Microtubule-Binding Protein that Is an Essential Component of the Yeast Spindle Pole Body
Previously we isolated tub2-423, a cold-sensitive allele of the Saccharomyces cerevisiae gene encoding beta-tubulin that confers a defect in mitotic spindle function. In an attempt to identify additional proteins that are important for spindle function, we screened for suppressors of the cold sensitivity of tub2-423 and obtained two alleles of a novel gene, STU2. STU2 is an essential gene and e...
متن کاملThe conserved protein kinase Ipl1 regulates microtubule binding to kinetochores in budding yeast.
Chromosome segregation depends on kinetochores, the structures that mediate chromosome attachment to the mitotic spindle. We isolated mutants in IPL1, which encodes a protein kinase, in a screen for budding yeast mutants that have defects in sister chromatid separation and segregation. Cytological tests show that ipl1 mutants can separate sister chromatids but are defective in chromosome segreg...
متن کاملSilver Resistance In Acinetobacter baumannii BL54 Occurs Through Binding to a Ag-Binding Protein
The mechanism of plasmid mediated silver (Ag) resistance was investigated in Acinetobacter baumanniiBL54. The intracellular accumulation of Ag in both original strain BL54 and Escherichia coli K12transconjugant containing plasmid pUPI276 began immediately and reached a maximum within 60 minutes.This initial accumulation was followed by net loss of Ag which reached a maximum wi...
