Predicted to enable GTP binding activity and GTPase activity. Acts upstream of or within histamine secretion by mast cell and histamine secretion mediated by IgE immunoglobulin. Predicted to be located in plasma membrane. Orthologous to human RAB44 (RAB44
Predicted to enable several functions, including GDP binding activity; GTPase activity; and TPR domain binding activity. Predicted to be involved in several processes, including endocytic recycling; positive regulation of corticotropin secretion; and protein import into peroxisome membrane. Located
in mitochondrion. Is expressed in brain; liver; and small intestine. Orthologous to human RAB8B (RAB8B, member RAS oncogene family). [provided by Alliance of Genome Resources, Jul 2025]
