Amino acid replacement: I271M.
Nucleotide substitution of ATG for ATA, (amino acid replacement of I by M) in the 425 amino stretch that is highly similar among DEAD-box proteins.
Oocytes from vas1 females express vas protein at normal levels throughout oogenesis.
lethal | maternal effect | recessive | heat sensitive
primordial germ cell | maternal effect
Temperature sensitivity is restricted to the abdominal phenotype: at the restrictive temperature embryos lack abdomens.
Progeny have no abdominal defects but still lack pole cells.
A weak vas allele.
