same xloc id but different tcons id with same exons

Hello,

I am trying to find differentially expressed genes bteween two samples and looked at the cuffcompare.combined.gtf file and noticed the following

chr9 Cufflinks exon 18970198 18970476 . + . gene_id "XLOC_001684"; transcript_id "TCONS_00002983"; exon_number "1"; gene_name "ENSCAFG00000010758"; oId "gonad.26568.1"; nearest_ref "ENSCAFT00000017124"; class_code "c"; tss_id "TSS1239";

Why am I getting different TCONS ids when the exon numbers are the same?

Thanks,
Joji

I noticed this too. If anyone could explain the differences between XLOC (gene id) and TCONS (transcript id), I'll really appreciate.

Essential Discoveries and Tools in Epitranscriptomics

by seqadmin

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...

Current Approaches to Protein Sequencing

by seqadmin

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...
