Stratifin Explained
Stratifin (also known as 14-3-3 protein sigma or 14-3-3σ protein) is a protein encoded by the SFN gene in humans.[1] [2] The protein is named for its presence in stratified epithelial cells.
Interactions
Stratifin has been shown to interact with PLK4,[3] ERRFI1,[4] MARK3,[3] [4] JUB[4] and YWHAG.[4]
