Protein existence	Evidence at transcript level

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.
