Atr-II, l(3)10460, TGF-β
receptor for Dpp - type II TGFß receptor - functions in both Dpp/BMP and Activin signaling - punt mutants lack Ultrabithorax and dpp expression in the visceral mesoderm and fail to induce labial in the adjacent endodermal cells - pathway specificity in signaling output is determined by which type I receptor (Dpp/BMP or Activin one) is engaged in the complex with Put

AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.

Interacts with babo; forms a heteromeric receptor complex that can bind the activin-like ligand Actbeta (PubMed:8289834). As part of the babo-put complex associates with Smox; dissociates upon phosphorylation of Smox (PubMed:10320478, PubMed:9887103). Interacts with tkv; forms a heteromeric receptor complex that can bind BMP-like ligands (PubMed:7697720). Interacts with sax; forms a heteromeric receptor complex that can bind BMP-like ligands (PubMed:7697720).
The basolateral targeting (BLT) motif within the cytoplasmic region determines basolateral membrane localization in wing disc epithelial cells.

The testis specificity index was calculated from modENCODE tissue expression data by Vedelek et al., 2018 to indicate the degree of testis enrichment compared to other tissues. Scores range from -2.52 (underrepresented) to 5.2 (very high testis bias).
put transcripts are detected throughout development on northern blots. They are abundant in nurse cells and in the developing oocyte. The transcript persists at high levels in the embryo until cellularization. Transcript levels decrease at cellularization but remain highest under the pole cells. At the start of gastrulation, transcripts are observed in the invaginating mesoderm. By stage 11, expression is observed along the entire length of the germ band in the mesoderm as well as in the developing gut. Expression continues in the fore- mid- and hindgut throughout most of embryogenesis. Third instar larval imaginal discs show prominant put expression.
put protein is observed throughout the embryo at syncytial blastoderm stage. At the start of gastrulation, Pburs protein is observed in the invaginating mesoderm. By stage 11 it is expressed along the entire length of the germ band in the mesoderm as well as in the developing gut. Expression continues in the fore- mid- and hindgut throughout most of embryogenesis.

Please Note This section lists cDNAs and ESTs that fall within the genomic extent of the gene model, which may include cDNAs and ESTs of genes within introns, or of overlapping genes. Please see JBrowse for alignment of the cDNAs and ESTs to the gene model.
For each fully sequenced cDNA the DGRC maintains various forms of the cDNA (e.g tagged or untagged) in several different host vectors for subsequent cloning and expression in Drosophila and Drosophila cell lines.
put is required during the late larval stage for development of adult-specific neurons.
dsRNA made from templates generated with primers directed against this gene tested in RNAi screen for effects on Kc167 and S2R+ cell morphology.
shn and put are required to limit transient amplification of germ cells. Mosaic analysis demonstrates shn and put act within somatic cyst cells that surround germ cells, rather than in germ cells. Thus a cyst-cell-derived signal restricts germ cell proliferation and this signal is initiated by input from a member of the TGF-β superfamily. Thus, a signal relay regulates progression through the germline stem cell lineage.
dpp receptors tkv and put are not required for photoreceptor cell differentiation. tkv and put play a nonessential role in morphogenetic furrow progression, but are required for initiation of the furrow at the posterior margin. Ectopic activation of the dpp pathway does not lead to ectopic neuronal differentiation.
Maternal and zygotic loss of put ventralises the embryo.
Mitotic recombination analysis demonstrates a requirement for maternal put gene product in dorsal-ventral patterning.
TGF-β like activity is present in cell extracts.
put mutants display failure of dorsal closure.
