In this paper they classify the promoters into two categories, highlighted in italics below.
Two Types of Promoters
Mammalian promoters can initiate transcription across broad or narrow genomic regions, and these promoter shapes, broad or narrow (sharp), correlate with distinct transcriptional regulatory mechanisms.33 We evaluated cardiac promoters predicted from CAGE clusters for these 2 major types of promoters by calculating the interquartile range of promoter CAGE clusters by determining the base pair distance between 10% and 90% of a promoter’s total signal. We observed the expected 2 distinct populations, defined as sharp (interquartile range <10 bp) and broad promoters (interquartile range ≥10 bp; Figure 2A). Broad promoters were those associated many different cellular functions, including housekeeping functions. In contrast, genes with sharp (narrow) promoters were those encoding proteins critical for tissue-specific functions seen by the presence myofilament, muscle tissue, and muscle contractions genes (Figure 2B). Thus, tissue-specific genes important for LV specification and function were more likely to have sharp promoters.
Now My question is can I do this only based on ATAC seq data. If yes how do i get that information of narrow and broad promoters.
