Protein attributes

Sequence length	34 AA.
Sequence status	Fragments.
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 By similarity. UniProtKB P84527
Subcellular location	Secreted By similarity.
Post-translational modification	Undergoes proteolytic cleavage by actinidin to produce kissper and KiTH. Three forms of KiTH are produced by cleavage at different sites. Ref.1
Allergenic properties	Causes an allergic reaction in human. Binds to IgE from the serum of kiwi-allergic patients. Ref.1
Sequence similarities	Belongs to the kiwellin family.
