WormMine: Gene WBGene00003370

• WormBase Gene ID: WBGene00003370
• Gene Name: mlc-2
• Sequence Name: C36E6.5
• Brief Description: mlc-2 encodes, along with mlc-1 and mlc-4, one of three C. elegans regulatory myosin light chains; MLC-2 is predicted to function as a regulator of myosin ATPase activity, and genetic studies indicate that MLC-2 is nearly essential in hermaphrodites for normal pharyngeal muscle function, but redundant with MLC-1, with which it is nearly identical, for proper bodywall muscle development; accordingly, loss of mlc-2 activity eventually results in larval lethality, as animals are not able to feed properly; mlc-2 mRNA is expressed in bodywall, pharyngeal, and vulval muscles.
• Organism: Caenorhabditis elegans
• Automated Description: Predicted to enable myosin heavy chain binding activity. Involved in several processes, including nematode larval development; regulation of muscle contraction; and regulation of nematode pharyngeal pumping. Predicted to be located in cytoplasm. Predicted to be part of myosin II complex. Expressed in body wall musculature; pharyngeal muscle cell; pharynx; and vulval muscle. Human ortholog(s) of this gene implicated in distal arthrogryposis type 1C and hypertrophic cardiomyopathy 10. Is an ortholog of human MYL10 (myosin light chain 10); MYL5 (myosin light chain 5); and MYL7 (myosin light chain 7).

	TGF- Dauer pathway adult transcriptional targets. Results obtained by comparing the microarray results of the dauer-constitutive mutants daf-7(e1372), daf-7(m62), and daf-1(m40) with dauer-defective mutants daf-3(mgDf90), daf-5(e1386), and daf-7(e1372);daf-3(mgDf90) double mutants at the permissive temperature, 20C, on the first day of adulthood.	SAM	WBPaper00031040:TGF-beta_adult_upregulated
	Genes that showed expression levels higher than the corresponding reference sample (embryonic 24hr reference).	A Mann-Whitney U test with an empirical background model and FDR correction for multiple testing was used to detect expressed transcripts (Benjamini and Hochberg 1995). Genes and TARs with an FDR <= 0.05 were reported as expressed above background. Authors detected differentially expressed transcripts using a method based on linear models. Genes and TARs were called differentially expressed if the FDR was <= 0.05 and the fold change (FC) >= 2.0. To more strictly correct for potential false-positives resulting from multiple sample comparisons, authors divided individual FDR estimates by the number of samplesor sample comparisons, respectively. This resulted in an adjusted FDR of 1.3 * 0.0001 for expression above background and of 7.4 * 0.0001 for differential expression. Authors called genes selectively enriched in a given tissue if they met the following requirements: (1) enriched expression in a given tissue (FDR <= 0.05 and FC >= 2.0), (2) fold change versus reference among the upper 40% of the positive FC range observed for this gene across all tissues, and (3) fold-change entropy among the lower 40% of the distribution observed for all genes.

	Genes with expression level regulated by genotype (N2 vs CB4856) and age at old adults stage (214 hours at 24 centigrade).	For model 2, authors used 100 permutations to estimate the FDR threshold. Per permutation, genotypes and ages were independently randomly distributed, keeping the among-gene structure intact. Then for each spot (23,232) on the array, model 2 was tested. The obtained P-values were used to estimate a threshold for each of the explanatory factors. Authors also used a genome-wide threshold of -log10 P-value = 2, which resembles an FDR of 0.072 and 0.060 for marker and the interaction age-marker for the developing worms and FDR of 0.050 and 0.065 for marker and age-marker for the aging worms. For the physiological age effect, authors used a log10 P-value = 8 in developing worms (0.012 FDR) and -log10 P-value = 6 (0.032 FDR).	WBPaper00040858:eQTL_age_regulated_aging

6 Expression Patterns

• Primary Identifier: Expr1031549
• Pattern: Tiling arrays expression graphs

• Primary Identifier: Expr2737
• Pattern: Hybridization of mlc probes to wild type demonstrated that mlc-2 is expressed in body-wall muscles, pharyngeal muscles, and vulval muscles. mlc-2 mRNA is present in all regions of the pharynx (procorpus, metacorpus, isthmus, and terminal bulb). mlc-2 mRNA was not detected in several of the minor muscle groups, such as the intestinal, uterine, anal depressor, and sphincter muscles, but these tissues were not well-preserved by the fixation methods. Similarly, mlc mRNA was not detected in nonmuscle cells, although such expression might be below detectable levels.
