This gene encodes a small GTPase of the Ras superfamily. Rab proteins are involved in the regulation of diverse cellular functions associated with intracellular membrane trafficking, including autophagy and immune response to bacterial infection. The encoded protein may play a role in central nervous system development by antagonizing sonic hedgehog signaling. Disruption of this gene has been implicated in Carpenter syndrome as well as cancer. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2013]
GeneCards Summary for RAB23 Gene
RAB23 (RAB23, Member RAS Oncogene Family) is a Protein Coding gene. Diseases associated with RAB23 include carpenter syndrome and cole-carpenter syndrome 2. Among its related pathways are Sertoli-Sertoli Cell Junction Dynamics and Hedgehog signaling events mediated by Gli proteins. GO annotations related to this gene include GTP binding and GTPase activity. An important paralog of this gene is RAB7B.
UniProtKB/Swiss-Prot for RAB23 Gene
The small GTPases Rab are key regulators of intracellular membrane trafficking, from the formation of transport vesicles to their fusion with membranes. Rabs cycle between an inactive GDP-bound form and an active GTP-bound form that is able to recruit to membranes different set of downstream effectors directly responsible for vesicle formation, movement, tethering and fusion. Together with SUFU, prevents nuclear import of GLI1, and thereby inhibits GLI1 transcription factor activity. Regulates GLI1 in differentiating chondrocytes. Likewise, regulates GLI3 proteolytic processing and modulates GLI2 and GLI3 transcription factor activity. Plays a role in autophagic vacuole assembly, and mediates defense against pathogens, such as S.aureus, by promoting their capture by autophagosomes that then merge with lysosomes.
