Protein attributes

Sequence length	233 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Zeins are major seed storage proteins.
Miscellaneous	The alpha zeins of 19 kDa and 22 kDa account for 70% of the total zein fraction. They are encoded by a large multigene family. Structurally, 22K and 19K zeins are composed of nine adjacent, topologically antiparallel helices clustered within a distorted cylinder.
Sequence similarities	Belongs to the zein family.
Sequence caution	The sequence CAA42105.1 differs from that shown. Reason: Erroneous termination at position 234. Translated as stop.
