FAM122B (Family with Sequence Similarity 122 Member B) is a gene located on chromosome 9 that encodes a protein involved in cellular signaling and regulation. FAM122B is known to interact with protein phosphatase 2A (PP2A), a critical enzyme in multiple signaling pathways, thereby impacting various cellular functions such as growth, division, and apoptosis. This interaction is pivotal for the modulation of PP2A activity, which in turn influences numerous downstream signaling processes. Studies have indicated that FAM122B may play a role in cancer biology, particularly in the regulation of oncogenic pathways. Dysregulation of FAM122B expression has been observed in certain cancers, suggesting its potential involvement in tumor progression and as a biomarker for diagnosis or prognosis. Furthermore, the gene's expression patterns indicate its importance in normal cellular homeostasis and the maintenance of cellular signaling balance.
