Type	Name	Post Left	Strand	Notes	Evidence (Confirmed, Strong, Weak)	References
promoter	TSS_1803 (cluster)	1490746	reverse	For this promoter, there is a cluster of 2 transcription start sites,in the interval 1490745 to 1490746, where the highest frequency is at position 1488770. The most upstream position of this cluster is assigned as TSS position in the promoter. Read more >	[RS-EPT-CBR]	[2]
