A mycobacterial smc null mutant is proficient in DNA repair and long-term survival.

چکیده
SMC (structural maintenance of chromosomes) proteins play fundamental roles in various aspects of chromosome organization and dynamics, including repair of DNA damage. Mutant strains of Mycobacterium smegmatis and Mycobacterium tuberculosis defective in SMC were constructed. Surprisingly, inactivation of smc did not result in recognizable phenotypes in hallmark assays characteristic for the function of these genes. This is in contrast to data for smc null mutants in other species.

Cti1/C1D interacts with condensin SMC hinge and supports the DNA repair function of condensin.
Condensin is a conserved five-subunit complex containing two SMC (structural maintenance of chromosomes) and three non-SMC subunits and plays a major role in mitotic chromosome condensation. Condensin also acts in interphase and is required for DNA repair and replication checkpoint control. We attempted to study the function of the condensin in greater detail by means of the isolation of intera...
متن کاملMain indications and long-term outcomes of reoperation after initial repair of tetralogy of Fallot
Background and Objective: The aim of this study was to analyze our indications, surgical procedures, and clinical outcomes of patients undergoing reoperation after surgical correction of tetralogy of Fallot (TOF). Methods: Thirty seven consecutive patients who underwent reoperation late after intra-cardiac repair of TOF within a period of 10 years were assessed. Results: The most co...
متن کاملThe Role of Ku70 in Regulating Cell Death During Cerebral Cortical Development
Ku70’s role in DNA repair is well-characterized and is critical for neuronal survival during cortical neurogenesis. Mice deficient in DNA repair exhibit elevated cell death of immature neurons during neurogenesis, demonstrating that young neurons have a high requirement for DNA repair. More recently, Ku70 has been demonstrated to bind and sequester Bax, a pro-apoptotic member of the Bcl-2 famil...
متن کاملThe Caulobacter crescentus smc gene is required for cell cycle progression and chromosome segregation.
The highly conserved SMC (Structural Maintenance of Chromosomes) proteins function in chromosome condensation, segregation, and other aspects of chromosome dynamics in both eukaryotes and prokaryotes. A null mutation in the Caulobacter crescentus smc gene is conditionally lethal and causes a cell cycle arrest at the predivisional cell stage. Chromosome segregation in wild-type and smc null muta...
متن کاملRestricted ultraviolet mutational spectrum in a shuttle vector propagated in xeroderma pigmentosum cells.
A shuttle vector plasmid, pZ189, carrying a bacterial suppressor tRNA marker gene, was treated with ultraviolet radiation and propagated in cultured skin cells from a patient with the skin-cancer-prone, DNA repair-deficient disease xeroderma pigmentosum and in repair-proficient cells. After replication in the human cells, progeny plasmids were purified. Plasmid survival and mutations inactivati...
