Vt20.1 (P03619) Protein Card

General Information
Name Vt20.1
Organism Conus vitulinus
Organism region Indo-Pacific
Organism diet vermivorous
Protein Type Wild type
Protein precursor Vt20.1 precursor (3618)
Notes Framework: This framework was assigned to be XII on discovery of VxXIIA , VxXIIB and VxXIIC 2006, which also had been used for conotoxins from the I superfamily (Brown et al. 2005). Loughnan et al. now propose framework designation XX (see reference).

Dimers: Mature D superfamily peptides form hetero-, homo- and pseudohomodimers (identical sequence, different posttranslational modifications). Entries for mature peptides in ConoServer are for monomers.
