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

Functioni

Cysteine protease that plays a role in immunity, senescence, and biotic and abiotic stresses (Probable). Involved in immunity against the necrotrophic fungal pathogen Botrytis cinerea (PubMed:22238602). Involved in elicitor-stimulated programmed cell death (PCD). During infection by the necrotrophic fungal pathogen Botrytis cinerea, functions as PCD-promoting protease that is released from the ER body or vacuole to the cytoplasm (PubMed:23398119). Accumulates in endoplasmic reticulum-derived bodies in epidermal cells and may participate in cell death in stressed or injured cells (PubMed:11577182). Involved in water stress-induced cell death through its protease activity that is released to the cytoplasm after vacuolar collapse (PubMed:26884487). Possesses protease activity in vitro and is involved in cell death in the transmitting tract and septum epidermis during flower development (PubMed:26160583). Possesses peptide ligase activity. Can ligate peptides to unmodified N-termini of acceptor proteins. Probably ligates through a thioester intermediate (PubMed:18660805).1 Publication6 Publications

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.
