Transcription unit       
Name: tsaB-yeaY
Synonym(s): yeaZY
Gene(s): yeaY, tsaB   Genome Browser M3D Gene expression COLOMBOS
Evidence: [ICWHO] Inferred computationally without human oversight
Promoter
Name: tsaBp
+1: Unknown
Note(s): Zaslaver et al. demonstrated in 2006, by means of a library of fluorescent transcription fusions, that this promoter can be transcribed in vitro Zaslaver A,2006. Based on this, a putative promoter was suggested, but the +1 site of the transcription initiation has not been determined, although there exists promoter activity.
Evidence: [IEP]
Reference(s): [3] Zaslaver A., et al., 2006


Evidence    

 [AIPP] Automated inference of promoter position

 [HIPP] Human inference of promoter position

 [TIM] Transcription initiation mapping

 [IEP] Inferred from expression pattern
