Summary: Enables Rab GDP-dissociation inhibitor activity and small GTPase binding activity. Involved in negative regulation of axonogenesis; positive regulation of axon extension; and response to calcium ion. Located in axon; myelin sheath; and neuronal cell body. Part of protein-containing complex. Is active in presynaptic cytosol.

What's a GeneRIF?

The expression and subcellular distribution of rab-GDI isoforms 1 is not significantly altered as AR42J cells differentiate into a more acinar cell-like phenotype.
Title: Hsp90 Co-localizes with Rab-GDI-1 and regulates agonist-induced amylase release in AR42J cells.
AlphaGDI interacts with a specialized membrane-associated Rab recycling Hsp90 chaperone system on the vesicle membrane to coordinate the Ca(2+)-dependent events triggering Rab-GTP hydrolysis with retrieval of Rab-GDP to the cytosol.
Title: Rab-alphaGDI activity is regulated by a Hsp90 chaperone complex.
T1-Rho GDI1 signaling was indispensable for regulating the activities of Rho GTPases and for the subsequent morphological changes among astrocytes.
Title: A truncated tropomyosin-related kinase B receptor, T1, regulates glial cell morphology via Rho GDP dissociation inhibitor 1.

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.
