This entry represents the N-terminal helical bundle domain from proteins in the TACO1/YebC family which are thought to act as transcriptional regulators. In mammals, The TACO1 protein activates the translation of mitochondrially-encoded COX1 [2,4]. In bacteria, it negatively regulates the quorum-sensing response regulator by binding to its promoter region [3].	Domain

In mammals, it activates the transcription of mitochondrially-encoded COX1 [2]. In bacteria, it negatively regulates the quorum-sensing response regulator by binding to its promoter region [3]. This ent ...	This is a family of transcriptional regulators. In mammals, it activates the transcription of mitochondrially-encoded COX1 [2]. In bacteria, it negatively regulates the quorum-sensing response regulator by binding to its promoter region [3]. This entry represents the second and third domains in this protein, with one domain nested within the other.	Domain
