WormBase Gene ID  ? WBGene00003335 Gene Name  mir-241
Sequence Name  ? F56A12.4 Brief Description  mir-241 encodes a microRNA, a small non-protein coding RNA and appears to have a potential ortholog in C. briggsae; based on RNA sequence identity, miR-241 belongs to the let-7 family of microRNAs along with C. elegans miR-48 and miR-84 and human let-7, miR-196-1 and miR-196-2; mir-241 acts redundantly with miR-48 and mir-84 to control L2 to L3 larval and larval to adult stage transitions; miR-241 is strongly expressed from the L3 larval stage into the adult stage in normal worms and in glp-4(bn2) mutant worms.
Organism  Caenorhabditis elegans Automated Description  Involved in miRNA-mediated gene silencing by inhibition of translation and positive regulation of development, heterochronic. Expressed in body wall musculature; excretory canal; hermaphrodite distal tip cell; and touch receptor neurons. Used to study Parkinson's disease.

  Potental DAF-12 target genes identified by ChIP-chip analysis performed on strain ALF4 [daf-12 Affymetrix TAS software that computed for each probe estimates of fold enrichment (in linear scale) over hybridization with input DNA. At the same time, TAS calculated for each probe a p-value by applying a Wilcoxon signed rank test. A threshold of 2.5 was selected, which corresponds to probe intensities approximately 2.5 times stronger on the ChIP array than on the Input array. Additional TAS threshold parameters were MinRun=180 bp, MaxGap=300 bp. TAS analysis showed that the selected threshold of 2.5 corresponds approximately to a p-value of 0.01.

11 Expression Patterns

Remark Reporter Gene Primary Identifier Pattern Subcellular Localization
In figure S2 expression is weak also in L1.   Expr10881 mir-241 is expressed in AVM and ALM touch neurons.  
    Expr12555    
    Expr8424 Expression detected from L1 till adulthood. Expressed in nerves: vnc, dnc, many in nerve ring, pharyngeal nerves and tail nerves. Also, expression seen in muscles from vulva, head, body and rectum and hypodermis.  
Picture: Fig 2A.   Expr8400 Northern blot temporal expression: L1 to adult.  
No expression was observed in mir-241(del)::gfp, which retains 0.73 kb of 5$(B!l(B sequence, indicating that regulatory sequences are present further upstream than for mir-48. Reporter gene fusion type not specified.   Expr3770 A mir-241::gfp fusion containing 1.3 kb 5$(B!l(B to the miR-241 coding sequence resulted in a temporally regulated, but largely spatially distinct, expression pattern from that of mir-48. Notably, hypodermal expression was not consistently observed. Body-wall muscle expression was first detected in L2-stage animals and continued to the adult stage. In the L3 stage, expression was detected in the excretory canal and the distal tip cells, and strong vulval expression was observed during the L4 stage.  
    Expr3740 Previous study reported that the let-7 family members, miR-84, miR-48, and miR-241, were expressed in a similar manner as the let-7 RNA, which was first detected during the L3 stage. However, this paper reveal that miR-241 and miR-48 both appeared one stage earlier than let-7 at eL2 with robust expression by L3. miR-84 appeared at low levels in the early L1 stage, was upregulated to an intermediate level in mid-L2, and had a high level of expression in early L4.  
Figure S4.   Expr12024 pri-mir-241 miRNA transcript levels oscillate during wild-type larval development, peaking once per larval stage.  
    Expr13379 In WT animals, miR-48, miR-241, and miR-237 miRNAs were expressed at very low levels during the L1, when LIN-14 is normally expressed, and increased in abundance 20- to 30-fold by the L3 when LIN-14 is down-regulated.  
Previous studies did not detect the four let-7 family members until the L3 stage, but earlier expression of all four microRNAs was detected by enhancing the sensitivity of detection.   Expr3771 When normalized to U6 expression, miR-241 reached half-maximal expression at about the L3 stage.  
    Expr12018    
    Expr2525 No signal detected in embryos, L1 and L2 larva. Intense signals detected in L3, L4 larva, adults, and glp-4(bn2) adults.
