Background

RAB27A (Ras-related protein Rab 27A; also GTP-binding protein Ram) is a 27-28 kDa member of the Rab27 subfamily, Rab family, Small GTPase superfamily of proteins. It is widely expressed, and found in cells diverse as mast cells, cytotoxic T cells, melanocytes, retinal pigment epithelium and pancreatic beta -cells. RAB27A plays a key role in the secretion of specialized lysosomes termed secretory lysosomes. In melanocytes, for example, RAB27A is incorporated into the melanosome membrane where it serves as a docking factor for melanophilin and myosin-Va, regulating melanosome transport to, and concentration at, sites of release. Human RAB27A is 221 amino acids (aa) in length. It contains multiple Rab family and subfamily motifs, and concludes with a C-terminal CXC prenylation sequence (aa 219‑221). There is one potential splice variant that shows a deletion of aa 146-153. Over aa 135-218, human RAB27A shares 92% and 94% aa sequence identity with mouse Rab27A and rat RAB27A, respectively.
