The gene downstream of receptor kinase is referred to in FlyBase by the symbol Dmel\drk (CG6033, FBgn0004638). It is a protein_coding_gene from Drosophila melanogaster. There is experimental evidence that it has the molecular function: protein binding; SH3/SH2 adaptor activity; sevenless binding. There is experimental evidence for 11 unique biological process terms, many of which group under: biological regulation; learning or memory; single-organism developmental process; associative learning; system process; regulation of developmental process; cognition; cellular component organization or biogenesis; post-embryonic organ morphogenesis; short-term memory. 40 alleles are reported. The phenotypes of these alleles are annotated with: organ system subdivision; organ system; larval abdominal segment; adult segment; region of integument; peripheral nervous system; imaginal precursor; external compound sense organ; abdominal 6 lateral pentascolopidial chordotonal organ lch5; abdominal 5 lateral pentascolopidial chordotonal organ lch5. It has 5 annotated transcripts and 5 annotated polypeptides. Protein features are: Neutrophil cytosol factor 2 p67phox; SH2 domain; Src homology-3 domain. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of high expression to a trough of moderate expression. Peak expression observed within 00-18 hour embryonic stages, during early pupal stages. Summary of FlyAtlas Anatomical Expression Data: Nearly all larval and adult tissues/organs expressed at moderate levels. Expression at high levels in the following post-embryonic organs or tissues: larval central nervous system, larval fat body, adult spermathecae. Expression at moderate levels in the following post-embryonic organs or tissues: adult head, adult eye, adult central nervous system, adult crop, larval/adult midgut, larval/adult hindgut, larval/adult Malpighian tubules, adult heart, adult fat body, larval/adult salivary gland, larval trachea, adult ovary, adult male accessory gland, larval/adult carcass. Comments on Affy2 ProbeSet: ProbeSet 1625475_s_at completely aligns to an exonic region common to each of the 6 FlyBase-annotated transcript isoforms of drk.

dos functions upstream or independent of Ras85D and defines a signalling pathway that is independent of direct binding of the drk SH2/SH3 adaptor protein to the sev receptor tyrosine kinase.
A high affinity binding site for the drk SH3 domain maps to the Sos product tail. The N-terminal drk SH3 domain is primarily responsible for binding to the tail of the Sos product in vitro, and for signalling to the Ras85D product in vivo.
Tyr2546 in the cytoplasmic tail of the sev protein is required for drk protein binding though a mutation in this site does not completely block sev function in vivo.
Wild type drk function is essential for signaling by the sev receptor tyrosine kinase. Its biological activity correlates with binding of its SH2 domain to activated receptor tyrosine kinases and concomitant localization to the plasma membrane. In vitro, drk binds the C terminal tail of the Sos (a Ras guanine nucleotide releasing protein) gene product through the drk SH3 domain, thereby linking receptor tyrosine kinases to Ras activation.
