Summary: Enables protein domain specific binding activity. Predicted to be involved in several processes, including complement-dependent cytotoxicity; regulation of vesicle-mediated transport; and secretion by cell. Predicted to act upstream of or within several processes, including leukocyte degranulation; melanocyte differentiation; and pigment granule localization. Located in Weibel-Palade body; apical plasma membrane; and secretory granule membrane. Human ortholog(s) of this gene implicated in Griscelli syndrome type 2 and non-Langerhans-cell histiocytosis. Orthologous to human RAB27A (RAB27A, member RAS oncogene family). [provided by Alliance of Genome Resources, Apr 2022]

Data show that the intracellular M4M5 loop of human alpha1 subunit of Na+,K+-ATPase (ATP1a1) interacts directly with rat rab GTP-binding protein Rab27a.
Title: A role for Na+,K+-ATPase α1 in regulating Rab27a localisation on melanosomes.
These findings indicated that Madd functions as a guanine nucleotide exchange factor for Rab27 in parotid acinar cells and regulates isoproterenol-stimulated amylase release.
Title: MADD/DENN/Rab3GEP functions as a guanine nucleotide exchange factor for Rab27 during granule exocytosis of rat parotid acinar cells.
cyt b(558) depends on clathrin for internalization, and in activated macrophages NADPH oxidase occupies a Rab27A/B-regulated secretory compartment
Title: NADPH oxidase is internalized by clathrin-coated pits and localizes to a Rab27A/B GTPase-regulated secretory compartment in activated macrophages.
Three Rab3/27 effectors, Granuphilin, Noc2, and Rabphilin, in PC12 cells using fluorescence recovery after photobleaching of EGFP-tagged proteins.
Title: The Rab27 effector Rabphilin, unlike Granuphilin and Noc2, rapidly exchanges between secretory granules and cytosol in PC12 cells.
Young secretory granules have a higher capacity for binding Rab3A and Rab27A is functionally important for preferential exocytosis from these granules.
Title: Differential dynamics of Rab3A and Rab27A on secretory granules.
Our results suggest that the Noc2/Rab27 complex is an important constituent of the early stages of IPR-stimulated amylase release.
Title: Functional involvement of Noc2, a Rab27 effector, in rat parotid acinar cells.
Rab27A interacts with Rabphilin and Noc2 which are recruited to dense-core vesicles in rat cells
Title: Rabphilin and Noc2 are recruited to dense-core vesicles through specific interaction with Rab27A in PC12 cells.
rab27a is a direct partner of munc13-4. The complex of the two proteins is an essential regulator of secretory granule fusion with the plasma membrane in hematopietic cells. Mutations in either of the two genes prevent formation of this compex.
Title: Munc13-4 is an effector of rab27a and controls secretion of lysosomes in hematopoietic cells.
Results demonstrate that Rab27A plays a crucial role in antigen-induced histamine release from RBL-2H3 cells.

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.
