Protein attributes

Sequence length	254 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Sequence similarities	Belongs to the Bowman-Birk serine protease inhibitor family.
Sequence caution	The sequence AAD10378.1 differs from that shown. Reason: Miscellaneous discrepancy. Chimeric cDNA. Its N-terminal part is derived from the gene LOC_Os01g03390, which encoded for an RBBI2.3 protein. The sequence BAD52869.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence BAF03803.1 differs from that shown. Reason: Erroneous gene model prediction.
