Taxonomic identifier	3627 [NCBI]
Taxonomic lineage	Eukaryota › Viridiplantae › Streptophyta › Embryophyta › Tracheophyta › Spermatophyta › Magnoliophyta › eudicotyledons › core eudicotyledons › asterids › Ericales › Actinidiaceae › Actinidia

Protein attributes

Sequence length	189 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Kissper is an anion-selective pore-forming peptide. Ref.2
Subcellular location	Secreted Potential.
Post-translational modification	Undergoes proteolytic cleavage by actinidin to produce kissper and KiTH. Three forms of KiTH are produced by cleavage at different sites, the main form produced in vivo is KiTH-1. Ref.3
Allergenic properties	Causes an allergic reaction in human. Binds to IgE from the serum of kiwi-allergic patients. Ref.1 Ref.3
Sequence similarities	Belongs to the kiwellin family.
