Type 2A phosphatase-associated protein 42

Gene

TAP42

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Involved in negative regulation of the TOR signaling pathway in response to type of available nitrogen source. Inhibitor of PP2A phosphatase SIT4, which results in inhibition of nuclear export of MSN2, due to lack of dephosphorylation by SIT4. Also required for rapamycin induced activation of expression of many nitrogen discrimination pathway (NDP) genes. In complex with PPH21, required for organization of the actin cytoskeletom during the cell cycle via a Rho GTPase-dependent mechanism.4 Publications

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.
