Gene Snapshot

G protein-coupled receptor kinase 2 (Gprk2) encodes a member of a family of serine/threonine kinases that modulate G-protein coupled receptors. It is required for female fertility, normal egg shape, and normal egg cAMP levels. It is also implicated in Hedgehog signaling and olfactory rhythmicity. [Date last reviewed: 2019-03-07]

Summaries

Gene Group (FlyBase)

AGC KINASES (UNCLASSIFIED) -: The AGC kinase subfamily are serine/threonine kinases that were originally defined based on the sequence similarity of the catalytic domain. The AGC KINASE (UNCLASSIFIED) gene group represents AGC kinases that do not fall into the PKA, PKC or PKG families. (Adapted from FBrf0132098 and PMID:20027184).

Pathway (FlyBase)

Positive Regulators of Hedgehog Signaling Pathway -: Positive regulators of hedgehog signaling down-regulation the pathway, enhancing the activation of transcription of hh-responsive genes.
Negative Regulators of Hedgehog Signaling Pathway -: Negative regulators of hedgehog signaling down-regulation the pathway, resulting in the repression of transcription of hh-responsive genes.
Positive Regulators of Toll-NF-κB Signaling Pathway -: In Drosophila, the canonical Toll signaling pathway is initiated by the binding of a spatzle ligand to Toll (Tl) or a Toll-like receptor leading to the nuclear localization of the NF-κB (dl or Dif) transcription factor. Positive regulators of Toll-NF-κB Signaling lead to the increased nuclear accumulation of the NF-κB proteins and regulated expression of target genes. (Adapted from FBrf0091014 and FBrf0223077).

Protein Function (UniProtKB)

Specifically phosphorylates the activated forms of G protein-coupled receptors (By similarity). Required during oogenesis and embryogenesis; component of a signaling pathway that functions during egg chamber maturation.

(UniProt, P32866)

Summary (Interactive Fly)

Pathways

Signaling Pathways (FlyBase)

Positive Regulators of Hedgehog Signaling Pathway -: Positive regulators of hedgehog signaling down-regulation the pathway, enhancing the activation of transcription of hh-responsive genes.
Negative Regulators of Hedgehog Signaling Pathway -: Negative regulators of hedgehog signaling down-regulation the pathway, resulting in the repression of transcription of hh-responsive genes.
Positive Regulators of Toll-NF-κB Signaling Pathway -: In Drosophila, the canonical Toll signaling pathway is initiated by the binding of a spatzle ligand to Toll (Tl) or a Toll-like receptor leading to the nuclear localization of the NF-κB (dl or Dif) transcription factor. Positive regulators of Toll-NF-κB Signaling lead to the increased nuclear accumulation of the NF-κB proteins and regulated expression of target genes. (Adapted from FBrf0091014 and FBrf0223077).
