ABTB1 (Ankyrin Repeat and BTB Domain Containing 1): ABTB1 is a protein that contains ankyrin repeats and a BTB (POZ) domain, suggesting its involvement in protein-protein interactions. It plays a role in regulating transcription and may contribute to the development of certain cancers. Although its complete range of functions is still under investigation, ABTB1 is associated with key cellular processes.
