Ras-related protein Rab-27A is a protein that in humans is encoded by the RAB27A gene.^[5]^[6]

Function

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 and hemophagocytic lymphohistiocytosis. Alternative splicing occurs at this locus and four transcript variants encoding the same protein have been identified.^[6]

The RAB27A gene is regulated by the Microphthalmia-associated transcription factor.^[7]^[8]

Interactions

RAB27A has been shown to interact with:

EXPH5,^[9]
MYO5A,^[10]^[11]
RPH3AL^[12]^[13]
SYTL1,^[9]^[14]^[15] and
SYTL2.^[9]^[14]^[15]
