WormMine: Gene WBGene00001599

• WormBase Gene ID: WBGene00001599
• Gene Name: glh-2
• Sequence Name: C55B7.1
• Brief Description: glh-2 encodes a putative DEAD-box RNA helicase that contains six CCHC zinc fingers and is homologous to Drosophila VASA, a germ-line-specific, ATP-dependent, RNA helicase; at non-permissive temperatures, GLH-2 plays a role in germ-line development and fertility, specifically in regulating the normal extent of germ-line proliferation, oogenesis, and the production of functional sperm; GLH-2 activity may also be required for the wild-type morphology of P granules and for localization of several protein components, but not accumulation of P granule mRNA components; GLH-2 interacts in vitro with itself and with KGB-1, a JNK-like MAP kinase; GLH-2 is a constitutive P granule component and thus, with the exception of mature sperm, is expressed in germ cells at all stages of development; GLH-2 is cytoplasmic in oocytes and the early embryo, while perinuclear in all later developmental stages as well as in the distal and medial regions of the hermaphrodite gonad; GLH-2 is expressed at barely detectable levels in males.
• Organism: Caenorhabditis elegans
• Automated Description: Enables JUN kinase binding activity and RNA helicase activity. Involved in germ cell development and post-embryonic development. Located in P granule. Expressed in germ line and gonad. Is an ortholog of human DDX4 (DEAD-box helicase 4).

	Maternal class (M): genes that are called present in at least one of the three PC6 replicates.	A modified Welch F statistic was used for ANOVA. For each gene, regressed error estimates were substituted for observed error estimates.

Regressed error estimates were abundance-dependent pooled error estimates that represented a median error estimate from a window of genes of similar abundance to the gene of interest. A randomization test was used to compute the probability Pg of the observed F statistic for gene g under the null hypothesis that developmental time had no effect on expression. P-values were not corrected for multiple testing.	[cgc5767]:expression_class_M

7 Expression Patterns

• Primary Identifier: Expr1030960
• Pattern: Tiling arrays expression graphs

• Primary Identifier: Expr1605
• Pattern: In adults, glh-1 and glh-2 RNAs are restricted to germ-line tissue. glh-1 RNA is present at all stages of germ-line development in the hermaphrodite gonad, from the distal region where germ cells divide mitotically through the proximal region where gametes mature. A similar pattern of strong glh-1 hybridization to all regions of the germ line is observed in males. The glh-2 message is at least 3-fold less abundant than glh-1 mRNA in the hermaphrodite germ line. The glh-2 signal is weakest in the distal mitotic region and most concentrated in the central meiotic region of the gonad. In addition, glh-2 RNA is barely detectable in males. Both glh-1 and glh-2 RNAs are detected in all cells of young embryos, with the level of hybridization much reduced after the 8- to 10-cell stage. Thus, while glh-1 and glh-2 RNA differ in their levels and their patterns of accumulation in hermaphrodite and male germ lines, both glh RNAs are found throughout the early embryo.

• Primary Identifier: Expr1606
• Subcellular Localization: Affinity-purified antibodies to either GLH-1 or GLH-2 proteins react with germ-line-specific P granules. P granules, as visualized by monoclonal antibodies directed against unidentified epitopes, are present in germ cells of all developmental stages with the exception of mature sperm. Anti-GLH-1 and anti-GLH-2 stain the same granules recognized by the anti-P-granule monoclonal antibodies; the granules are cytoplasmic in the oocyte and early embryo and perinuclear in later stage embryos. In adult worms, anti-GLH-1 brightly stains perinuclear P granules throughout the germ line of hermaphrodites and males. Anti-GLH-2 shows a more restricted pattern of staining that corresponds to the RNA distribution seen in situ; staining is less intense in the distal region than in the meiotic region of hermaphrodites and is barely detectable in the male germ line. P-granule staining is not detected with any preimmune sera or yolk.
