Protein attributes

Sequence length	184 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Accepts the ubiquitin-like protein NEDD8/RUB1 from the ECR1-AXR1 E1 complex and catalyzes its covalent attachment to other proteins.
Catalytic activity	ATP + NEDD8 + protein lysine = AMP + diphosphate + protein N-NEDD8yllysine.
Pathway	Protein modification; protein neddylation.
Subunit structure	Interacts with RBX1.
Tissue specificity	Expressed in shoot, root and floral meristems, and in vascular tissues of leaves.
Miscellaneous	Reduction in RCE1 levels leads to reduced organ length and defects in gravitropism.
Sequence similarities	Belongs to the ubiquitin-conjugating enzyme family. UBC12 subfamily.
Sequence caution	The sequence CAB16820.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAB80346.1 differs from that shown. Reason: Erroneous gene model prediction.

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]

Isoform 1 (identifier: Q9SDY5-1)

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.

Isoform 2 (identifier: Q9SDY5-2)

The sequence of this isoform differs from the canonical sequence as follows:
     102-184: YHPNIDLEGN...VGQTFFPRCI → GLSSFYMPYI...FGRKRLPEHL

Notes: May be due to intron retention. No experimental confirmation available.
