Protein ajuba is a protein that in humans is encoded by the JUB gene.^[3][4]

Function

JUB proteins contribute to cell fate determination and regulate cell proliferation and differentiation. Plays an important role in regulation of the kinase activity of AURKA/Aurora-A for mitotic commitment.

Interactions

JUB (gene) has been shown to interact with Stratifin^[5] and SLC1A2.^[6]
