Protein

Ras-like protein 2

Gene

RAS2

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

The S.cerevisiae Ras proteins modulate the activity of the adenylate cyclase catalytic subunit and therefore affect the biosynthesis of cyclic-AMP.

Enzyme regulationi

Alternates between an inactive form bound to GDP and an active form bound to GTP. Activated by guanine nucleotide-exchange factor (GEF) CDC25 and inactivated by GTPase-activating proteins (GAPs) IRA1 and IRA2.

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.
