Probable ubiquitin-conjugating enzyme E2 24

Gene

UBC24

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Accepts the ubiquitin from the E1 complex and catalyzes its covalent attachment to other proteins (By similarity). Mediates PHO1 degradation through multivesicular body-mediated vacuolar proteolysis in response to inorganic phosphate (Pi) availability (PubMed:22634761). Negatively regulates the protein abundance of PHF1 and PHT1s under Pi-sufficient conditions by facilitating the degradation of PHT1 proteins at the endomembrane (PubMed:24122829).By similarity2 Publications

Catalytic activityi

S-ubiquitinyl-[E1 ubiquitin-activating enzyme]-L-cysteine + [E2 ubiquitin-conjugating enzyme]-L-cysteine = [E1 ubiquitin-activating enzyme]-L-cysteine + S-ubiquitinyl-[E2 ubiquitin-conjugating enzyme]-L-cysteine.Curated

MicroRNA399 (miR399) can be sequestered by IPS1, a non-protein coding RNA containing a motif with sequence complementarity to miR399, but with a mismatched loop at the expected miRNA cleavage site. Thus IPS1 mimics the target of miR399 to block the cleavage of UBC24/PHO2 under Pi-deficient conditions.1 Publication

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.
