靶标
-
功能Plays a role in cytotoxic granule exocytosis in lymphocytes. Required for both granule maturation and granule docking and priming at the immunologic synapse.
-
组织特异性Found in all the examined tissues except in brain. Low expression was found in thymus, kidney, muscle and placenta. Detected in melanocytes, and in most tumor cell lines examined. Expressed in cytotoxic T-lymphocytes (CTL) and mast cells.
-
疾病相关Defects in RAB27A are a cause of Griscelli syndrome type 2 (GS2) [MIM:607624]. Griscelli syndrome is a rare autosomal recessive disorder that results in pigmentary dilution of the skin and hair, the presence of large clumps of pigment in hair shafts, and an accumulation of melanosomes in melanocytes. GS2 patients also develop an uncontrolled T-lymphocyte and macrophage activation syndrome, known as hemophagocytic syndrome, leading to death in the absence of bone marrow transplantation. Neurological impairment is present in some patients, likely as a result of hemophagocytic syndrome.
-
序列相似性Belongs to the small GTPase superfamily. Rab family.
-
细胞定位Membrane. Melanosome. Late endosome. Lysosome. Identified by mass spectrometry in melanosome fractions from stage I to stage IV. Localizes to endosomal exocytic vesicles.

Western blot - Anti-RAB27A antibody (ab55667)Lane 1: Wild type HAP1 whole cell lysate (20 µg)
Lane 2: RAB27A knockout HAP1 whole cell lysate (20 µg)
Lane 3: Jurkat whole cell lysate (20 µg)
Lane 4: MCF7 whole cell lysate (20 µg)Lanes 1 - 4: Merged signal (red and green). Green - ab55667 observed at 27 kDa. Red - loading control, ab181602, observed at 37 kDa.
ab55667 was shown to specifically react with RAB27A when RAB27A knockout samples were used. Wild-type and RAB27A knockout samples were subjected to SDS-PAGE. Ab55667 and ab181602 (Rabbit anti GAPDH loading control) were incubated overnight at 4°C at 2.5 ug/ml and 1/10000 dilution respectively. Blots were developed with IRDye® 800CW Goat anti-Mouse IgG (H + L) and IRDye® 680 Goat anti-Rabbit IgG (H + L) secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.

Immunocytochemistry/ Immunofluorescence - Anti-RAB27A antibody (ab55667)This image is courtesy of an Abreview submitted by Dr Vladimir Milenkovicab55667 staining cow Retinal Pigment Epithelium (RPE) cells by ICC/IF. Cells were PFA fixed and permeabilized in 0.5% Triton X-100 prior to blocking in 10% serum for 20 minutes at 25°C. The primary antibody was diluted 1/200 and incubated with the sample for 12 hours at 4°C. An Alexa Fluor® 546 conjugated goat anti-mouse antibody was used as the secondary. Rab27a, which localizes to the apical site of the RPE cells, is labeled with red fluorescence. Nuclei were counterstained with DAPI (blue).
