一般說明
Rab27 (Ras-related protein) is a member of the Rab family of small guanosine triphosphatases (GTPases). Rab27 is widely expressed in non-neuronal regulated secretory cells, including exocrine, endocrine, ovarian, and hematopoietic cells.
Rab27A (Ras-related protein) belongs to the Rab family of small GTPase proteins. It is located on chromosome 15q21.
免疫原
synthetic peptide corresponding to amino acid residues 45-57 of human RAB27A, with an added cysteine, conjugated to KLH. The corresponding sequence differs by one amino acid in rat and mouse Rab27A and by 2 amino acids in human RAB27B.
應用
Anti-Rab27 (N-terminal) antibody has been used in immunoblotting, immunofluorescence.
生化／生理作用
In humans, Rab27A (Ras-related protein) plays important roles in the development of cancers. It is considered as a prognostic biomarker for CRC (colorectal cancer) patients. It may participate in the transfer of protein and signal transduction mediated by GTPase. Rab27 mutation is linked with Griscelli syndrome type 2. It is also responsible for the innate immune resistance against invading microorganisms.
Rab27 (Ras-related protein) regulates the exocytosis of these cell-specific store organelles, using multiple organelle-specific effector proteins, such as granuphilin and melanophilin.

Exosomes are extracellular vesicles that influence cellular behavior and enhance cancer aggressiveness by carrying bioactive molecules. The mechanisms that regulate exosome secretion are poorly understood. Here, we show that the actin cytoskeletal regulatory protein cortactin promotes exosome secretion. Knockdown or

Mast cell degranulation is regulated by the small guanosine triphosphatases (GTPases) Rab27a and Rab27b, which have distinct and opposing roles: Rab27b acts as a positive regulator through its effector protein Munc13-4, a non-neuronal isoform of the vesicle-priming Munc13 family of
