General annotation (Comments)

Function

Causes loosening and extension of plant cell walls by disrupting non-covalent bonding between cellulose microfibrils and matrix glucans. No enzymatic activity has been found. Required for normal plant growth. May be required for rapid internodal elongation in deepwater rice during submergence. Ref.7

Subcellular location

Secretedcell wall By similarity. Membrane; Peripheral membrane protein By similarity.

Tissue specificity

Expressed in lateral root primordia, adventitious root primordia, coleoptiles, shoot apex, leaf primordia, very young leaves, panicles and flowers. Ref.6 Ref.9

Induction

By gibberellin (GA3), submergence and wounding. Ref.6

Disruption phenotype

Plants are smaller. Ref.7

Sequence similarities

Belongs to the expansin family. Expansin A subfamily.

Contains 1 expansin-like CBD domain.

Contains 1 expansin-like EG45 domain.
