ddx-19 encodes a DEAD-box helicase; ddx-19(RNAi) in a mpk-1(ga111ts) mutant background results in germline developmental defects, including disruption of membrane organization in pachytene cells and disorganized oocytes; DDX-19 can be phosphorylated by murine ERK2 in vitro, suggesting that it is a substrate for the RTK-RAS-ERK pathway in vivo; consistent with this, DDX-19 phosphorylation is absent in mpk-1 mutant animals; DDX-19 localizes to perinuclear P granules.
Predicted to enable RNA binding activity and RNA helicase activity. Involved in germ cell development. Located in P granule. Expressed in tail. Is an ortholog of human DDX19A (DEAD-box helicase 19A) and DDX19B (DEAD-box helicase 19B).
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
