Summary: ADP-ribosylation factor (ARF)-like proteins (ARLs) comprise a functionally distinct group of the ARF family of RAS-related GTPases. The protein encoded by this gene binds to ARL2.GTP with high affinity but does not interact with ARL2.GDP, activated ARF, or RHO proteins. The lack of detectable membrane association of this protein or ARL2 upon activation of ARL2 is suggestive of actions distinct from those of the ARFs. This protein is considered to be the first ARL2-specific effector identified, due to its interaction with ARL2.GTP but lack of ARL2 GTPase-activating protein activity. [provided by RefSeq, Jul 2008]

ARL3 activation requires the co-GEF BART and effector-mediated turnover.

Study identified multiple ciliopathy phenotypes associated with mutations in ARL2BP in human patients and in a mouse knockout model. Spermiogenesis is impaired, resulting in abnormally shaped heads, shortened and mis-assembled sperm tails, and loss of axonemal doublets. ARL2BP is required for the structural maintenance of cilia as well as of the sperm flagellum, and that its deficiency leads to syndromic ciliopathy.
Title: Mutations in ARL2BP, a protein required for ciliary microtubule structure, cause syndromic male infertility in humans and mice.
This study identified two homozygous variants in ARL2BP as a rare cause of autosomal recessive retinitis pigmentosa. Further studies are required to define the underlying disease mechanism causing retinal degeneration as a result of mutations in ARL2BP and any phenotype-genotype correlation associated with residual levels of the wild-type transcript.
Title: Novel homozygous splicing mutations in ARL2BP cause autosomal recessive retinitis pigmentosa.
Subsequent analysis of 844 index cases did not reveal further pathogenic chances in ARL2BP indicating that mutations in ARL2B are a rare cause of arRCD (about 0.1%) in a large cohort of French patients.
Title: ARL2BP mutations account for 0.1% of autosomal recessive rod-cone dystrophies with the report of a novel splice variant.
Alteration of EBV encoded miR-BART1 expression results in an increase in migration and invasion of nasopharyngeal carcinoma in vitro and causes metastasis in vivo. EBV-miR-BART1 directly targets the cellular tumour suppressor PTEN.

Our results imply that BART regulates actin-cytoskeleton rearrangements at membrane ruffles through modulation of the activity of Rac1, which, in turn, inhibits pancreatic cancer cell invasion.
Title: BART inhibits pancreatic cancer cell invasion by Rac1 inactivation through direct binding to active Rac1.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
