Rabbit anti-Human UBA6 Polyclonal Antibody

Uniprot Id

A0AVT1

Target Species

Human

Target Name

UBA6

Target Full Name

Ubiquitin-like modifier-activating enzyme 6

Target Function

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. Specific for ubiquitin, does not activate ubiquitin-like peptides. Differs from UBE1 in its specificity for substrate E2 charging. Does not charge cell cycle E2s, such as CDC34. Essential for embryonic development. Required for UBD/FAT10 conjugation. Isoform 2 may play a key role in ubiquitin system and may influence spermatogenesis and male fertility.

Target Protein Families

Ubiquitin-activating E1 family

Target Tissue Specificity

Widely expressed. Isoform 2 is predominantly expressed in testis with higher expression in adult testis than in fetal testis.

Target Background

Modification of proteins with ubiquitin (UBB; MIM 191339) or ubiquitin-like proteins controls many signaling networks and requires a ubiquitin-activating enzyme (E1), a ubiquitin conjugating enzyme (E2), and a ubiquitin protein ligase (E3). UBE1L2 is an E1 enzyme that initiates the activation and conjugation of ubiquitin-like proteins (Jin et al., 2007 [PubMed 17597759]).
