Ras-related protein Rab-27A is a protein that in humans is encoded by the RAB27A gene.[3][4]

Function[edit]

The protein encoded by this gene belongs to the small GTPase superfamily, Rab family. The protein is membrane-bound and may be involved in protein transport and small GTPase mediated signal transduction. Mutations in this gene are associated with Griscelli syndrome type 2. Alternative splicing occurs at this locus and four transcript variants encoding the same protein have been identified.[4]

The RAB27A gene is regulated by the Microphthalmia-associated transcription factor.[5][6]

Interactions[edit]

RAB27A has been shown to interact with:
