Functioni

Zinc metalloprotease that exhibits a weak hemorrhagic activity (with a minimum hemorrhagic dose of 20 µg by intradermal and intramuscular injection into mice). The basal membrane components collagen (all chains of type IV) (COL4A4), laminin and nidogen are all degraded by this toxin (PubMed:23385358). Rapidly degrades the Aalpha-chain (FGA) of fibrinogen, and later on, degrades the Bbeta-chain (FGB) of fibrinogen (PubMed:7778126). Also activates the complement system, and induces rat neutrophil chemotaxis (PubMed:11200361). Induces edema in mouse food pad and a mild myotoxicity (PubMed:7778126).4 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.
