May control the transcriptional activity of MYC. Stimulates the activation of E box-dependent transcription by MYC.
Subcellular locations: Cytoplasm, Nucleus, Mitochondrion
Translocates into the nucleus in the S phase of the cell cycle upon an increase of MYC expression. Found in the mitochondria when associated with AKAP1.
Highly expressed in heart, placenta, pancreas, skeletal muscle and kidney. Also present at low levels in lung.
