High-throughput screen for small molecules that modulate the ATPase activity of the molecular chaperone DnaK.
DnaK is a molecular chaperone of Escherichia coli that belongs to a family of conserved 70-kDa heat shock proteins. The Hsp70 chaperones are well known for their crucial roles in regulating protein homeostasis, preventing protein aggregation, and directing subcellular traffic. Given the complexity of functions, a chemical method for controlling the activities of these chaperones might provide a...
متن کاملAPAF 1 ( Apoptotic protease activating factor 1 )
Five isoforms of APAF1 cDNA have been identified in Homo sapiens: The original APAF1 (also called Apaf-1S) is 3585 bp long (it contains 12 WD40 repeats); The APAF1-1M isoform (3618 bp) contains an insertion of 33 nt after position 295 of the first published sequence (11 aa insertion GKDSVSGITSY between aa 98 and 99; it also contains 12 WD40 repeats); The APAF1XS isoform (3516 bp) contains the s...
متن کاملIsolation of Helicobacter pylori genes that modulate urease activity.
Helicobacter pylori urease, a nickel-requiring metalloenzyme, hydrolyzes urea to NH3 and CO2. We sought to identify H. pylori genes that modulate urease activity by constructing pHP8080, a plasmid which encodes both H. pylori urease and the NixA nickel transporter. Escherichia coli SE5000 and DH5alpha transformed with pHP8080 resulted in a high-level urease producer and a low-level urease produ...
متن کاملA comparison of the expression and properties of Apaf-1 and Apaf-1L.
Apaf-1 is a mammalian homolog of CED-4 that regulates cell death by participating in a ternary complex with cytochrome c, and procaspase-9. In the case of CED-4, two splice variants exist. The smaller (CED-4S) is proapoptotic while the larger (CED-4L) contains a short in-frame insert and is anti-apoptotic. We cloned a murine variant of apaf-1, termed apaf-1L, which contains an eleven amino acid...
متن کاملHistone deacetylase activity regulates apaf-1 and caspase 3 expression in the developing mouse retina.
PURPOSE Apoptosis is a form of programmed cell death essential for both tissue development and maintenance of tissue homeostasis. Apoptosis protease activating factor (Apaf)-1 and caspase 3 are downregulated in the retina during postnatal development. The decreased expression of these genes is potentially a critical survival strategy adopted to protect against accidental cell death. The purpose...
