Official Symbol: isp-1
Official Full Name: Cytochrome b-c1 complex subunit Rieske, mitochondrial
Primary source: WormBase:WBGene00002162
Locus tag: CELE_F42G8.12
See related: AllianceGenome:WB:WBGene00002162
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Caenorhabditis elegans (strain: Bristol N2)

Summary: Predicted to enable oxidoreductase activity. Involved in several processes, including mitochondrial electron transport, ubiquinol to cytochrome c; regulation of gene expression; and regulation of protein phosphorylation. Predicted to be located in mitochondrial inner membrane. Predicted to be part of respiratory chain complex III. Is expressed in several structures, including enteric muscle; intestine; nervous system; rectal epithelium; and reproductive system. Human ortholog(s) of this gene implicated in mitochondrial complex III deficiency. Orthologous to human UQCRFS1 (ubiquinol-cytochrome c reductase, Rieske iron-sulfur polypeptide 1) and UQCRFS1P1 (ubiquinol-cytochrome c reductase, Rieske iron-sulfur polypeptide 1 pseudogene 1).

What's a GeneRIF?

Gating and control processes influence the function of ISP-1 in mediating pleiotropic phenotypes including developmental rate, movement, sensitivity to stress, and longevity.
Title: Tether mutations that restore function and suppress pleiotropic phenotypes of the C. elegans isp-1(qm150) Rieske iron-sulfur protein.
stress response, and/or fecundity of isp-1(qm150) Mit mutants relative to wild-type animalsstress response, and/or fecundity of isp-1(qm150) Mit mutants relative to wild-type animals
Title: TAF-4 is required for the life extension of isp-1, clk-1 and tpk-1 Mit mutants.
ROS production by mitochondrial mutants and found that isp-1 and nuo-6 mutants have increased generation of the superoxide anion but not increased levels of other ROS and that this increase is necessary and sufficient for longevity.
Title: A mitochondrial superoxide signal triggers increased longevity in Caenorhabditis elegans.
found that the lifespan increase induced by nuo-6(RNAi) is fully additive to that induced by isp-1(qm150), and the increase induced by isp-1(RNAi) is fully additive to that induced by nuo-6(qm200)
Title: Two modes of mitochondrial dysfunction lead independently to lifespan extension in Caenorhabditis elegans.
