Protein attributes

Sequence length	907 AA.
Sequence status	Complete.
Protein existence	Evidence at transcript level

General annotation (Comments)

Function	Accepts the ubiquitin from the E1 complex and catalyzes its covalent attachment to other proteins By similarity. Ref.2 Ref.8
Catalytic activity	ATP + ubiquitin + protein lysine = AMP + diphosphate + protein N-ubiquityllysine.
Pathway	Protein modification; protein ubiquitination.
Tissue specificity	Expressed in the vascular tissues of cotyledons, leaves, roots, sepals, filaments, anthers and junctions between the inflorescence stems and siliques. Ref.2 Ref.3
Developmental stage	Up-regulated in senescing leaves and maturating seeds. Ref.2
Induction	Down-regulated by phosphate deprivation. Ref.2 Ref.3 Ref.8
Disruption phenotype	Plants are unable to regulate the amount of phosphate accumulated into shoots. Ref.3
Miscellaneous	Systemic regulation by microRNA399 (miR399).
Sequence similarities	Belongs to the ubiquitin-conjugating enzyme family.
Sequence caution	The sequence AAC69130.1 differs from that shown. Reason: Erroneous gene model prediction.
