Protein

Guanine nucleotide-binding protein G(T) subunit gamma-T1

Gene

GNGT1

Organism
Bos taurus (Bovine)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Guanine nucleotide-binding proteins (G proteins) are involved as a modulator or transducer in various transmembrane signaling systems. The beta and gamma chains are required for the GTPase activity, for replacement of GDP by GTP, and for G protein-effector interaction.

Caution

In PubMed:3917402 the authors propose that Cys-36 and Cys-37 are disulfide bonded because they could not be observed during peptide sequencing, but were observed after reduction by dithiothreitol and reaction with labeled iodoacetamide. The crystallographic structures do not support these cysteines being disulfide bonded. Artifactual oxidation and some other cysteine modifications might be consistent with these observations.Curated

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.
