WormBase Gene ID  ? WBGene00021416 Gene Name  mksr-2
Sequence Name  ? Y38F2AL.2 Brief Description  mkrs-2 encodes an ortholog of human B9D2 (OMIM:611951), paralogous to MKRS-1 and MKS-1; MKRS-2 is required for fully normal foraging behavior, and is redundantly required with NPH-4 for roughly normal foraging, and with both NPH-1 and NPH-4 for cilia formation; MKRS-2 is expressed in most ciliated cells, including amphid, phasmid, and labial-quadrant neurons, in a DAF-19-dependent manner; MKRS-2 forms a complex with MKRS-1 and MKS-1 at the base of cilia, and is coexpressed with these proteins in ciliated sensory neurons; MKRS-2 protein is required for proper localization of MKRS-1 and MKS-1 to the transition zone, and binds MKRS-1 in two-hybrid assays.
Organism  Caenorhabditis elegans Automated Description  Involved in several processes, including determination of adult lifespan; larval foraging behavior; and non-motile cilium assembly. Located in ciliary basal body; ciliary transition zone; and dendrite terminus. Expressed in neurons. Used to study Joubert syndrome. Human ortholog(s) of this gene implicated in Joubert syndrome. Is an ortholog of human B9D2 (B9 domain containing 2).

  Transcripts that showed significantly increased expression in L1 neural cells comparing to in adult neural cells. DESeq2 (v1.18.1) fold change > 2, P-adj<0.05, using BenjaminiHochberg correction. WBPaper00060811:L1_vs_adult_upregulated_neural
  Transcripts of coding genes that showed significantly decreased expression in muscle. DESeq2 (version 1.24.0). Transcripts with a false-discovery rate adjusted p-value less than 0.05 were considered significantly differentially expressed. WBPaper00062325:muscle_depleted_coding-RNA
  Transcripts expressed in neuronal cells, by analyzingfluorescence-activated cell sorted (FACS) neurons. DESeq. False discovry rate (FDR) < 0.1. WBPaper00048988:neuron_expressed
  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 L3 larva and Late reproduction stage (96 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_developing
  Genes with expression level regulated by genotype (N2 vs CB4856) at Late reproduction stage (96 hours at 24 centigrade).

  Transcripts that showed significantly increased expression in ubc-9(ne4833[ubc-9(G56R)] in gonads dissected from 1-day old adult animals. Salmon was used to map the mRNA-seq reads with the worm database WS268, and its output files were imported to DESeq2 in R. The differentially expressed genes were filtered by fold change more than 2 and adjusted p-value < 0.05. The scatter plots were generated by the plot function in R.

    Expr8174 Utilizing transgenic lines coexpressing transcriptional fusions xbx-7::YFP and tza-1::CFP or xbx-7::YFP and tza-2::CFP, authors observed expression of these genes specifically in ciliated sensory neurons and additionally found that their expression was overlapping.  
Promoter::GFP fusion constructs of variable lengths were generated using PCR amplification followed by subsequent cloning into expression vectors.   Expr10104 Expressed in both the amphid and tail ciliated sensory neurons. The 60 C. elegans CSNs present in an adult hermaphrodite worm were divided into 5 subgroups or anatomical regions including, neurons that reside in the amphids (region 1 = 24 CSNs: AWAL/R, AWBL/R, AWCL/R, AFDL/R, ASEL/R, ADFL/R, ASGL/R, ASHL/R, ASIL/R, ASJLR, ASKL/R, ADLL/R) or in the tail (region 2 = 5 CSNs: PHAL/R, PHBL/R, PQR), neurons surrounding the anterior bulb (region 3 = 24 CSNs: BAGL/ R, CEPVL/R, CEPDL/R, IL1L/R, IL2L/R, IL1VL/R, IL2VL/R, IL1DL/R, IL2DL/R, OLLL/R, OLQVL/R, OLQDL/R) or the posterior bulb (region 4 = 5 CSNs: ADEL/R, FLPL/R, AQR) of the pharynx, and neurons in the midbody region of the worm (region 5=2 CSNs: PDEL/R). tza-1 was detected in all 5 regions.

Picture: Fig. 2C.   Expr8531 The three mks/mksr transgenes were expressed specifically in most, if not all ciliated cells, including the amphid and phasmid sensory neurons. The three GFP-tagged proteins (MKS-1, MKSR-1 and MKSR-2) localized specifically to transition zones at the base of cilia, which are akin to the basal bodies of other species. For each amphid bundle, authors were able to observe up to ~12 transition zones as fluorescent spots near the head of the animal; for the phasmid sensory neurons situated near the tail, two pairs of transition zones could be seen. This localization pattern is equivalent to that observed for the mammalian orthologues except that the latter proteins could also associate with the ciliary axonemes.
