Description
FOSBis a protein that, in humans, is encoded by the FOSB gene. The Fos genefamily consists of 4 members: FOS, FOSB, FOSL1, and FOSL2. These genes encodeleucine zipper proteins that can dimerize with proteins of the JUN family,thereby forming the transcription factor complex AP-1. As such, the FOSproteins have been implicated as regulators of cell proliferation,differentiation, and transformation
