WormMine: Gene WBGene00000212

• WormBase Gene ID: WBGene00000212
• Gene Name: asm-2
• Sequence Name: ZK455.4
• Brief Description: asm-2 encodes a protein similar to human acid sphingomyelinase (ASM) or sphingomyelin phosphodiesterase 1; the ASM-2 protein has a putative secretory signal peptide at the N-terminus, saposin-like and proline-rich domains and putative N-linked glycosylation sites; asm-2 shows phosphodiesterase activity when expressed in COS-7 cells; like mammalian ASM, asm-2 is probably both intracellular and secreted; northern blot analysis indicates that asm-2 is expressed during post-embryonic development as compared to asm-1 which is expressed at higher levels in the embryo; human ASM is implicated in Niemann-Pick disease type B (OMIM:607608).
• Organism: Caenorhabditis elegans
• Automated Description: Enables sphingomyelin phosphodiesterase activity. Involved in ceramide biosynthetic process and sphingomyelin catabolic process. Located in extracellular region. Human ortholog(s) of this gene implicated in Niemann-Pick disease type A and Niemann-Pick disease type B. Is an ortholog of human SMPD1 (sphingomyelin phosphodiesterase 1).

	Genes that were downregulated in lin-15B(n744).	For each gene in each microarray hybridization experiment, the ratio of RNA levels from the two samples was transformed into a log2 value and the mean log2 ratio was calculated. The log2 ratios were normalized by print-tip Loess normalization (Dudoit and Yang, 2002). All genes with a false discovery rate of <= 5% (q <= 0.05) (Storey and Tibshirani, 2003) and a mean fold-change ratio of >= 1.5 were selected for further analysis.
