Rabbit anti-Human TRIM23 Polyclonal Antibody

Uniprot Id

P36406

Target Species

Human

Target Name

TRIM23

Target Full Name

E3 ubiquitin-protein ligase TRIM23

Target Function

Acts as an E3 ubiquitin-protein ligase. Plays an essential role in autophagy activation during viral infection. Mechanistically, activates TANK-binding kinase 1/TBK1 by facilitating its dimerization and ability to phosphorylate the selective autophagy receptor SQSTM1. In order to achieve this function, TRIM23 mediates 'Lys-27'-linked auto-ubiquitination of its ADP-ribosylation factor (ARF) domain to induce its GTPase activity and its recruitment to autophagosomes.; (Microbial infection) Mediates TRAF6 auto-ubiquitination in the presence of human cytomegalovirus protein UL144, resulting in the virally controlled activation of NF-kappa-B stimulation at early times of HCMV infection.

Target Subcellular Location

Cytoplasm. Endomembrane system. Golgi apparatus membrane. Lysosome membrane. Note=Membrane-associated with the Golgi complex and lysosomal structures.

Target Background

The protein encoded by this gene is a member of the tripartite motif (TRIM) family. The TRIM motif includes three zinc-binding domains, a RING, a B-box type 1 and a B-box type 2, and a coiled-coil region. This protein is also a member of the ADP ribosylation factor family of guanine nucleotide-binding family of proteins. Its carboxy terminus contains an ADP-ribosylation factor domain and a guanine nucleotide binding site, while the amino terminus contains a GTPase activating protein domain which acts on the guanine nucleotide binding site. The protein localizes to lysosomes and the Golgi apparatus. It plays a role in the formation of intracellular transport vesicles, their movement from one compartment to another, and phopholipase D activation. Three alternatively spliced transcript variants for this gene have been described.
