RIN belongs to the RAS (HRAS; MIM 190020) superfamily of small GTPases (Shao et al., 1999).[supplied by OMIM]^[7]

RIT2 has been associated with Parkinson's disease in two large genetic studies.^[8][9] An gene expression study of postmortem brain has suggested RIT2 interacts with interferon-γ signalling.^[10]

Interactions

RIT2 has been shown to interact with POU4F1.^[11]
