Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
Based on sequence similarity, it is predicted to have molecular function: methionine adenosyltransferase activity.
There is experimental evidence that it is involved in the biological process: bristle development; wing disc development; S-adenosylmethionine biosynthetic process.
12 alleles are reported.
The phenotypes of these alleles are annotated with: eye; trichogen cell; macrochaeta; male genitalia; mesothoracic tergum; scutellar bristle; tergite.
It has 11 annotated transcripts and 11 annotated polypeptides.
Protein features are: S-adenosylmethionine synthetase; S-adenosylmethionine synthetase superfamily; S-adenosylmethionine synthetase, C-terminal; S-adenosylmethionine synthetase, N-terminal; S-adenosylmethionine synthetase, central domain; S-adenosylmethionine synthetase, conserved site.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of very high expression to a trough of moderately high expression.
Peak expression observed at stages throughout embryogenesis, during early larval stages, in adult female stages.
