Taxonomic lineage

cellular organisms › Eukaryota › Viridiplantae › Streptophyta › Streptophytina › Embryophyta › Tracheophyta › Euphyllophyta › Spermatophyta › Magnoliophyta › eudicotyledons › core eudicotyledons › asterids › lamiids › Solanales › Solanaceae › Solanoideae › Solaneae › Solanum

Protein attributes

Sequence length	66 AA.
Sequence status	Fragment.
Protein existence	Evidence at transcript level

General annotation (Comments)

Tissue specificity	In tubers of untreated plants. After ABA treatment or mechanical wounding is mostly accumulated in leaves, to a lesser extent in stems, but not in roots.
Induction	By abscisic acid (ABA), jasmonic acid (JA) and wounding.
Sequence similarities	Belongs to the cystatin family. Phytocystatin subfamily.
