WormMine: Gene WBGene00002134

• WormBase Gene ID: WBGene00002134
• Gene Name: inx-12
• Sequence Name: ZK770.3
• Brief Description: inx-12 (innexin=invertebrate connexin analogue) encodes a protein of the innexin family; innexins are gap junction proteins similar in function, though dissimilar in sequence to the vertebrate connexins; innexins are the only known gap junction proteins in invertebrates; inx-12 and inx-13 appear to be a tandom duplication; RNA interference of inx-12 results in an arrest at the L1 larval stage with fluid filled dead rods; this phenotype and sequence homology to Drosophila innexins suggest that INX-12 may be required to form gap junctions between the excretory canal and hypodermis, thus playing an essential role in osmoregulation; an INX-12::GFP fusion protein is expressed in the excretory canal.
• Organism: Caenorhabditis elegans
• Automated Description: Predicted to enable gap junction hemi-channel activity. Involved in positive regulation of nematode male tail tip morphogenesis. Predicted to be located in gap junction and plasma membrane. Expressed in several structures, including head ganglion; interfacial epithelial cell; neurons; posterior lateral ganglion; and tail hypodermis.

	Maternal class (M): genes that are called present in at least one of the three PC6 replicates.	A modified Welch F statistic was used for ANOVA. 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

	Strictly maternal class (SM): genes that are the subset of maternal genes that are not also classified as embryonic.	A modified Welch F statistic was used for ANOVA. 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.
