Gene Snapshot
saxophone (sax) encodes a type I BMP receptor. Together with the BMP receptors encoded by tkv and put, it transduces signaling of the BMP ligands encoded by dpp, gbb and scw, in a wide variety of developmental processes including embryonic and imaginal disc patterning.

Pathway (FlyBase)
BMP Signaling Pathway Core Components -
The Bone Morphogenetic Protein (BMP) signaling pathway is one of two branches of Transforming Growth Factor-β family signaling in Drosophila. The binding of a BMP family dimer to a heterodimeric serine/threonine kinase receptor complex results in the phosphorylation of Mad, a member of the Smad family. Mad forms a complex with the co-Smad, Med. This complex translocates into the nucleus and regulates the transcription of target genes in concert with other nuclear cofactors. (Adapted from FBrf0236482.)
Gene Group (FlyBase)
TGF-BETA TYPE I RECEPTORS -
The Transforming Growth Factor-β Receptor (TGF-βR) family are transmembrane serine/threonine kinases. They form heterodimeric receptor complexes composed of type I and type II subunits. Upon ligand binding, the constitutively active type II receptor phosphorylates the type I receptor which, in turn, phosphorylates a member of the Smad family. (Adapted from FBrf0236482.)
Phenotypic Description (Red Book; Lindsley and Zimm 1992)
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).
Summary (Interactive Fly)

receptor s/t kinase - a type I Dpp receptor - necessary for the specification of the dorsal-most cell fate (amnioserosa) which requires the highest levels of Dpp activity - together with the BMP receptors Tkv and Put, Sax transduces signaling of the BMP ligands Dpp, Gbb and Scw in the embryo and in imaginal disc patterning

Additional Descriptive Data

sax transcripts are expressed ubiquitously in all tissues and at all stages of development.

(Brummel et al., 1994)

Uniform sax expression was observed in early embryos. While the levels decline in later embryos, expression remains ubiquitous.

          BMP Signaling Pathway Core Components -
          The Bone Morphogenetic Protein (BMP) signaling pathway is one of two branches of Transforming Growth Factor-β family signaling in Drosophila. The binding of a BMP family dimer to a heterodimeric serine/threonine kinase receptor complex results in the phosphorylation of Mad, a member of the Smad family. Mad forms a complex with the co-Smad, Med. This complex translocates into the nucleus and regulates the transcription of target genes in concert with other nuclear cofactors.

          dsRNA made from templates generated with primers directed against this gene tested in RNAi screen for effects on Kc167 and S2R+ cell morphology.

          (Kiger et al., 2003)

          Loss of function alleles of sax suppress the CycEJP mutant eye phenotype.

          (Horsfield et al., 1998)

          dpp/tkv signaling is obligatorily required, while scw/sax signaling is necessary but not sufficient for dorsal patterning in the embryo.

          (Nguyen et al., 1998)

          Mutations in dpp or its receptor sax accelerate germline stem cell loss and retard stem cell division.

          (Xie and Spradling, 1998)

          sax protein functions similarly in the anterior and posterior compartment. sax regulates salm through its role in anterior posterior patterning of the wing pouch.

          (Singer et al., 1997)

          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.

          (Singer et al., 1997)

          grk and sax function control dpp expression in the posterior follicular epithelium during oogenesis.

          (Twombly et al., 1996)

          sax is required in the germline for oogenesis to proceed normally.

          (Twombly et al., 1996)

          There is at least partial overlap of function of the sax and tkv receptors in vivo.

          (Brummel et al., 1994)

          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.

          (Nellen et al., 1994)

          Isolated in a PCR screen for receptor protein serine/threonine kinase candidates.

          (Penton et al., 1994)

          Mutations in sax result in a maternal effect phenotype with defects during the early stages of gastrulation.
