The gene saxophone is referred to in FlyBase by the symbol Dmel\sax (CG1891, FBgn0003317). It is a protein_coding_gene from Drosophila melanogaster. There is experimental evidence that it has the molecular function: transforming growth factor beta receptor activity, type I. There is experimental evidence for 15 unique biological process terms, many of which group under: single-organism developmental process; biological regulation; multicellular organism reproduction; regionalization; gamete generation; ovarian follicle cell development; regulation of developmental process; system development; cellular component organization or biogenesis; anterior/posterior axis specification; post-embryonic organ morphogenesis; negative regulation of response to stimulus. 53 alleles are reported. The phenotypes of these alleles are annotated with: organ system; adult segment; organ system subdivision; thoracic segment; synapse; external compound sense organ; imaginal precursor; extended germ band embryo; portion of tissue; non-connected developing system; epithelial furrow; spiracle; late extended germ band embryo. It has 3 annotated transcripts and 3 annotated polypeptides. Protein features are: Protein kinase, ATP binding site; Protein kinase, catalytic domain; Protein kinase-like domain; Serine/threonine-protein kinase, active site; TGF beta receptor, GS motif; TGF-beta receptor/activin receptor, type I/II. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of high expression to a trough of low expression. Peak expression observed within 00-12 hour embryonic stages. Summary of FlyAtlas Anatomical Expression Data: High or moderate levels of expression observed in all larval and adult organs/tissues. Expression at high levels in the following post-embryonic organs or tissues: adult ovary. Expression at moderate levels in the following post-embryonic organs or tissues: adult head, adult eye, larval/adult central nervous system, adult crop, larval/adult midgut, larval/adult hindgut, larval/adult Malpighian tubules, adult heart, larval/adult fat body, larval/adult salivary gland, larval trachea, adult spermathecae, adult male reproductive system, larval/adult carcass. Comments on Affy2 ProbeSet: ProbeSet 1633805_a_at completely aligns to an exonic region common to each of the 2 FlyBase-annotated transcript isoforms of sax. Gene sequence location is 2R:3693989..3697572.

Phenotypic Description from the Red Book (Lindsley
& Zimm 1992)
Gene/Allele symbols may differ
from current usage
sax: saxophone (T. Schupbach and E. Wieschaus)
Maternal effect lethal, female sterile. Embryos
from homozygous mothers gastrulate abnormally. The cephalic
furrow is more pronounced than in wildtype. The phenotype is
reminiscent of the zygotic embryonic lethal mutaton twisted
gastrulaton (twg).

sax protein functions similarly in the anterior and posterior compartment. sax regulates salm through its role in anterior posterior patterning of the wing pouch.
sax protein participates in the determination of the anterior posterior margin fate in the developing wing pouch, even at the extreme anterior edge. sax and tkv interact with the same developmental pathways required for proper anterior posterior patterning of the wing.
Specification of distinct cell fates in response to different concentrations of dpp product may be achieved combinatorially by the sax and tkv receptors. sax is required for the specification of the amnioserosa.
