The gene Guanylyl cyclase α-subunit at 99B is referred to in FlyBase by the symbol Dmel\Gycα99B (CG1912, FBgn0013972). It is a protein_coding_gene from Drosophila melanogaster. There is experimental evidence that it has the molecular function: guanylate cyclase activity. There is experimental evidence that it is involved in the biological process: rhodopsin mediated signaling pathway; positive phototaxis. 11 alleles are reported. The phenotypes of these alleles are annotated with: photoreceptor cell R7; photoreceptor cell R8. It has one annotated transcript and one annotated polypeptide. Protein features are: Adenylyl cyclase class-3/4/guanylyl cyclase; Adenylyl cyclase class-3/4/guanylyl cyclase, conserved site; Haem NO binding associated; Heme-NO binding; NO signalling/Golgi transport ligand-binding domain. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of moderately high expression to a trough of extremely low expression. Peak expression observed within 18-24 hour embryonic stages, during early larval stages, during late pupal stages. Summary of FlyAtlas Anatomical Expression Data: Expression at high levels in the following post-embryonic organs or tissues: adult central nervous system. Expression at moderate levels in the following post-embryonic organs or tissues: adult head, adult eye, larval central nervous system. Comments on Affy2 ProbeSet: ProbeSet 1641618_at completely aligns to an exonic region of the only FlyBase-annotated transcript isoform of Gycalpha99B. Gene sequence location is 3R:25508225..25511480.

Coexpression of Gycα99B protein and
Gycβ100B protein in human kidney cells results in significant guanylyl
cyclase activity. No activity is observed if either is introduced alone.
Results indicate that Gycα99B protein and Gycβ100B protein are
soluble guanylyl cyclase alpha and beta subunits that are capable of
forming a functional guanylyl cyclase heterodimer.
Gycα99 protein is detected in adult heads and at very low levels in bodies on western blots. Immunolocalization to adult tissue sections shows expression in the optic lobe, central brain, and thoracic ganglia.
Gycα99B protein is expressed in the retina and underlying optic lobes of the adult visual system. In addition, a diffuse pattern of staining is observed throughout the adult brain neuropil.
Summary of FlyAtlas Anatomical Expression Data: Expression at high levels in the following post-embryonic organs or tissues: adult central nervous system. Expression at moderate levels in the following post-embryonic organs or tissues: adult head, adult eye, larval central nervous system.

This section lists
cDNAs and ESTs that fall within the genomic extent

of genes within introns, or of overlapping genes.

to the gene model.
Gyc-89Db shows no guanylyl cyclase activity when expressed in COS-7 cells in the absence of additional subunits, in the presence of either Mg2+ or Mn2+ cofactor. When Gyc-89Db and Gycα99B are co-expressed in COS-7 cells in the presence of either Mg2+ or Mn2+, no guanylyl cyclase activity is detected.
