Uba1y

Ubiquitin-like modifier-activating enzyme 1 Y

1058 amino acids

Activates ubiquitin by first adenylating its C-terminal glycine residue with ATP, and thereafter linking this residue to the side chain of a cysteine residue in E1, yielding a ubiquitin-E1 thioester and free AMP (By similarity). The Y chromosome form could be involved in the survival and proliferation of differentiating spermatogonia.

Belongs to the ubiquitin-activating E1 family.
