cox-5b encodes the ortholog of the nuclear-encoded cytochrome c oxidase-1 subunit Vb/COX4, a component of the electron transport chain in mitochondria; knock-down of cox-5b via RNA interference in specific tissues like body wall muscle decreases life span, whereas knock-down in the nervous system and intestine increases life-span; the effects of cox-5b on life span indicate that the electron transport chain functions in a tissue-specific manner to affect the aging process, and studies show that this effect is dependent on the mitochondrial unfolded protein response.
Predicted to enable metal ion binding activity. Involved in determination of adult lifespan; lipid storage; and proton motive force-driven mitochondrial ATP synthesis. Predicted to be located in mitochondrial envelope. Predicted to be part of mitochondrial respiratory chain complex IV. Is an ortholog of human COX5B (cytochrome c oxidase subunit 5B).
This gene was formerly known as lpd-4 and was renamed following advice from the CGC. [krb 030512]
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
