WormMine: Gene WBGene00003886

• WormBase Gene ID: WBGene00003886
• Gene Name: osm-6
• Sequence Name: R31.3
• Brief Description: osm-6 encodes a novel protein that is orthologous to the IFT52 component of the intraflagellar transport particle; osm-6 activity is required cell autonomously for proper sensory cilium structure and thus for normal ciliated sensory neuron function; OSM-6 is a component of the intraflagellar transport particle subcomplex B, and OSM-6::GFP reporter fusions are expressed exclusively in ciliated sensory neurons.
• Organism: Caenorhabditis elegans
• Automated Description: Involved in several processes, including cellular response to salt; non-motile cilium assembly; and sensory perception of mechanical stimulus. Located in cilium; cytoplasm; and neuronal cell body. Expressed in neurons. Human ortholog(s) of this gene implicated in asphyxiating thoracic dystrophy. Is an ortholog of human IFT52 (intraflagellar transport 52).

	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.

15 Expression Patterns

• Primary Identifier: Marker99
• Remark: Picture: Fig 2D, 2E.
• Pattern: Marker for ASEL and ASER neurons.

• Primary Identifier: Marker73
• Remark: Picture: Figure 4A, 4B. Reporter gene fusion type not specified.
• Subcellular Localization: Marker for the amphid and phasmid cilia.

• Primary Identifier: Expr7645
• Remark: Clone: pUL#JS1G1
• Pattern: Weak expression is seen in the nerve cell bodies and nerve cell processes of the head and tail region. Expression is seen from mid stage embryos onwards.

• Primary Identifier: Expr507
• Remark: Included upstream of gfp in the fusion gene was 5.1 kb of osm-6 genomic sequence, extending from 2.4 kb upstream of the 5' end of the osm-6 cDNA through the first 10 exons and all introns into the last exon, such that only the last 13 codons, including the translational stop, of OSM-6 were lacking. Transgenic Marker: rol-6(su1006) late embryo(author) = fully-elongated embryo(curator).
• Pattern: Expressed in 56 cells in the hermaphrodite: the 24 amphid neurons, twelve inner labial neurons, six outer labial neurons, four CEP cells, two ADE cells, four phasmid cells in all stages from late embryo through adult; AQR and PQR at L1 through adult PDE cells at L2 through adult. Additional expression in male-specific cells: CEM cells and male tail sensory cells.

• Primary Identifier: Expr8093
• Remark: Picture: Figure 3.
• Subcellular Localization: GFP fusion protein was localized throughout the AWB cilia.

• Primary Identifier: Expr10117
• Remark: Promoter::GFP fusion constructs of variable lengths were generated using PCR amplification followed by subsequent cloning into expression vectors.
• Pattern: 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). osm-6 was detected in all 5 regions.

• Primary Identifier: Expr3028
• Pattern: KAP::GFP, OSM-1::GFP, and OSM-6::GFP fusion proteins are expressed in amphid and phasmid chemosensory neurons.
• Subcellular Localization: They appear to concentrate at the base of the transition zones, which correspond to the basal bodies of motile and sensory cilia. These fusion proteins are seen to emerge from the transition zones as small fluorescent particles that move in a bidirectional fashion along the sensory cilia, displaying anterograde movement from the transition zone toward the tip of the ciliary axoneme and retrograde movement from the cilium tip back toward the transition zone.

• Primary Identifier: Expr12033
• Pattern: The cilium structural gene osm-6 is expressed in both HOA (P10.pppa) and HOB (P10.ppap).

• Primary Identifier: Expr13933
• Pattern: The transcriptional reporter using the promoter region of the cilia specific gene osm-6 (Posm-6) is expressed in both the PQR as well as the URX neuron.

• Primary Identifier: Expr1155663
• Pattern: Developmental gene expression time-course. Raw data can be downloaded from ftp://caltech.wormbase.org/pub/wormbase/datasets-published/hashimshony2015

• Primary Identifier: Expr15146
• Pattern: Consistent with redundant functions of these motors in building the AWA cilium, KAP-1::GFP and OSM-3::GFP could be detected throughout the AWA cilia in wild-type animals. However, KAP-1::GFP was preferentially enriched in the short proximal AWA ciliary stalk with low expression levels in the distal ciliary branches, whereas OSM-3::GFP accumulated strongly at the distal tips of the AWA ciliary branches. A GFP-tagged OSM-6 IFT-B fusion protein was also present at low levels throughout AWA cilia but was enriched in the proximal stalk similar to KAP-1::GFP.
