InnateDB Annotation
TRIM23 mediates K(lys)-27-ubiquitin conjugation to IKBKG (NEMO) which is essential for TLR3- and RIG-I/MDA5-mediated antiviral innate and inflammatory responses.
TRIM23 was identified in a systematic screen for positive regulators of innate immune responses.
Entrez Gene
Summary 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. [provided by RefSeq, Jul 2008]
