NCBI Protein Information
E1 C-terminal related 1
NCBI Summary
Encodes a subunit of a RUB-activating enzyme analogous to the E1 ubiquitin-activating enzyme. ECR1 functions as a heterodimer with AXR1 to activate RUB, a ubiquitin-related protein.
UniProt Protein Name

UniProt Comments
Catalytic subunit of the dimeric ECR1-AXR1 E1 enzyme. E1 activates NEDD8/RUB1 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-ECR1 thioester and free AMP. E1 finally transfers NEDD8 to the catalytic cysteine of RCE1 .
