Functioni

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 (By similarity). 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 (By similarity). 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.By similarity5 Publications

Pathology & Biotechi

Involvement in diseasei

Defects in Rab23 are the cause of the open brain phenotype. Mice suffer from exencephaly and severe malformations of the spinal cord and the dorsal root ganglia, leading to complete embryonic lethality. In addition, mice display poorly developed eyes and polydactyly.

Disruption phenotypei

Complete embryonic lethality, due to defects in neural tube closure. Mice suffer from exencephaly and severe malformations of the spinal cord and the dorsal root ganglia. In addition, mice display poorly developed eyes and polydactyly.2 Publications

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
