Acts as a coactivator of MAFF transcriptional activity. Inhibits cell growth and colony-forming efficiency.
Subcellular locations: Cytoplasm, Nucleus, Nucleolus
Interaction with MAFF induces its translocation from the cytoplasm to the nucleolus.
Strongly expressed in brain, kidney and ovary. Moderately expressed in liver, spleen, thymus, prostate, testis, small intestine and colon. Weakly expressed in heart, placenta, lung and leukocytes.
