Regulation of Rad51 function by phosphorylation.
Rad51 is a key enzyme involved in DNA double-strand break repair by homologous recombination. Here, we show that in response to DNA damage, budding yeast Rad51 is phosphorylated on Ser 192 in a manner that is primarily mediated by the DNA-damage-responsive protein kinase Mec1. We show that mutating Rad51 Ser 192 to Ala or Glu confers hypersensitivity to DNA damage and homologous-recombination d...
متن کاملATM/ATR-mediated phosphorylation of PALB2 promotes RAD51 function.
DNA damage activates the ATM and ATR kinases that coordinate checkpoint and DNA repair pathways. An essential step in homology-directed repair (HDR) of DNA breaks is the formation of RAD51 nucleofilaments mediated by PALB2-BRCA2; however, roles of ATM and ATR in this critical step of HDR are poorly understood. Here, we show that PALB2 is markedly phosphorylated in response to genotoxic stresses...
متن کاملRegulation of cardiac contractile function by troponin I phosphorylation.
Cardiac troponin I (cTnI) is a key regulatory protein in cardiac muscle contraction and relaxation, linking Ca(2+)-troponin C binding with activation of crossbridge reactions with the thin filament. In recent years, it has become increasingly apparent that myofilament properties as well as changes in intracellular Ca(2+) have a major role in the dynamic modulation of contractile function. The p...

15 صفحه اولDown-Regulation of T Cell Function by Heat Shock-Induced Excretory Factor of Leishmania Major
Background: Despite demonstration of molecular and biochemical changes induced by heat shock on Leishmania, the immunological importance of such changes has not been elucidated. Objective: Studying the effect of two excretory factors prepared under heat shock and ambient temperature from Leishmania major on Balb/c splenocytes function. Methods: The parasites were cultured at 25°C and then sub...
