Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome. This score <strong>cannot</strong> be used as a measure of the accuracy of the annotation as we cannot define the 'correct annotation' for any given protein.<p><a href='/help/annotation_score' target='_top'>More...</a></p>
-Experimental evidence at protein leveli <p>This indicates the type of evidence that supports the existence of the protein.

<p>This section provides any useful information about the protein, mostly biological knowledge.<p><a href='/help/function_section' target='_top'>More...</a></p>Functioni

Catalytic subunit of the dimeric Uba3-APP-BP1 E1 enzyme. E1 activates Nedd8 by first adenylating its C-terminal glycine residue with ATP, thereafter linking this residue to the side chain of the catalytic cysteine, yielding a Nedd8-Uba3 thioester and free AMP. E1 finally transfers Nedd8 to the catalytic cysteine of UbcE2M. Required for Cul1 and Cul3 neddylation. Negatively regulates full-length ci stability and hedgehog signaling.

<p>The checksum is a form of redundancy check that is calculated from the sequence.
