Hi i am new. I just noticed that some papers define the region within 1 kb to TSS as "near TSS: while the region over 1kb as "far away from TSS". what 's the speciality of the "1kb" ? especially when one protein owns regions "near TSS" and "far awya from TSS" are there any expected difference?

The 1Kb distance is pretty arbitrary, in fact you'll find a range of distances in different papers (I've seen up to 5kb upstream to maybe 2kb downstream). There are typically some proteins that bind closer to the actual TSS than others, but the exact distances used to discriminate between things isn't really set in stone.

The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...04-22-2024, 07:01 AM -
Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...04-04-2024, 04:25 PM
