Guanine nucleotide-binding protein subunit alpha homolog

Gene

cta

Organism
Drosophila melanogaster (Fruit fly)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at transcript leveli

Functioni

May play a role in a signal transduction pathway used during gastrulation. Required specifically for the ventral furrow and posterior midgut invaginations, where it is necessary for coordinating cell shape changes.1 Publication
Guanine nucleotide-binding proteins (G proteins) are involved as modulators or transducers in various transmembrane signaling systems.1 Publication

Expressioni

Tissue specificityi

In ovary, expressed in nurse cells and oocyte. In early embryos, distributed uniformly. At the extended germband stage, accumulates in the mesoderm.1 Publication

Developmental stagei

Expressed throughout oogenesis. In early embryos, expression drops during cellularization, remains low throughout gastrulation and increases once germband extension has begun.1 Publication

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
