Protein attributes

Sequence length	290 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at transcript level

General annotation (Comments)

Function	May cause loosening and extension of plant cell walls by disrupting non-covalent bonding between cellulose microfibrils and matrix glucans. No enzymatic activity has been found. May be required for rapid internodal elongation in deepwater rice during submergence By similarity.
Subcellular location	Secreted › cell wall By similarity. Membrane; Peripheral membrane protein By similarity.
Tissue specificity	Expressed in flowers. Ref.7
Sequence similarities	Belongs to the expansin family. Expansin A subfamily. Contains 1 expansin-like CBD domain. Contains 1 expansin-like EG45 domain.
Sequence caution	The sequence AAL24497.1 differs from that shown. Reason: Erroneous initiation. The sequence AAM52408.1 differs from that shown. Reason: Erroneous initiation.
