WormMine: Gene WBGene00015248

• WormBase Gene ID: WBGene00015248
• Gene Name: mai-2
• Sequence Name: B0546.1
• Brief Description: mai-2/B0546.1 is orthologous to mitochondrial intrinsic ATPase inhibitorprotein (IF(1)), which blocks reverse action (ATP hydrolysis) byF(0)F(1)-ATPase when its (normally required) proton gradient is lost;MAI-2 has a mitochondrial import signal at its N-terminus, and istransported to yeast mitochondria; MAI-2 can inhibit yeastF(0)F(1)-ATPase, and this inhibition is pH-dependent; MAI-2's tertiarystructure is dominated by beta-strands and random loops.
• Organism: Caenorhabditis elegans
• Automated Description: Enables ATPase inhibitor activity. Predicted to be involved in heme biosynthetic process. Located in mitochondrion. Expressed in germ line and tail. Is an ortholog of human ATP5IF1 (ATP synthase inhibitory factor subunit 1).

For each gene, regressed error estimates were substituted for observed error estimates. The substitution is justified by the lack of consistency among the most and least variable genes at each time point. Regressed error estimates were abundance-dependent pooled error estimates that represented a median error estimate from a window of genes of similar abundance to the gene of interest. A randomization test was used to compute the probability Pg of the observed F statistic for gene g under the null hypothesis that developmental time had no effect on expression. P-values were not corrected for multiple testing.	[cgc5767]:expression_class_M

• Pattern: MAI-2::GFP expression was observed in the cytoplasm at all the embryonic and post-embryonic stages in what seems to be a mitochondrial pattern. The expression of MAI-2::GFP was observed in the germline and all somatic tissues, including neurons, pharynx, the intestine, body wall muscle and the hypodermis, during C. elegans development. MAI-2::GFP co-localized with mitochondria in the gonad and embryos. We found a clear co-localization of MAI-2::GFP with the mitochondrial probe in the hypodermis and muscle.
