BRD2

bromodomain containing 2

NCBI Gene: 6046 Ensembl GeneCards UniProt: P25440

Pathway candidate — not linked to PFS or PSSD by any record here

BRD2 is in the library because it belongs to the epigenetic regulation family. No study, report or commentary in the corpus names it, so a variant in BRD2 is not, by itself, evidence of anything related to post-drug syndromes.

Gene summary

A protein-coding gene on chromosome 6 (epigenetic regulation). Encodes a transcriptional regulator that belongs to the BET (bromodomains and extra terminal domain) family of proteins. This protein associates with transcription complexes and with acetylated chromatin during mitosis, and it selectively binds to the acetylated lysine-12 residue of histone H4 via its two bromodomains.

Protein reference (UniProt)

Protein: Bromodomain-containing protein 2
Function (excerpt): Chromatin reader protein that specifically recognizes and binds histone H4 acetylated at 'Lys-5' and 'Lys-12' (H4K5ac and H4K12ac, respectively), thereby controlling gene expression and remodeling chromatin structures. Recruits transcription factors and coactivators to target gene sites, and activates RNA polymerase II machinery for transcriptional elongation. Plays a key role in genome compartmentalization via its association with CTCF and cohesin: recruited to chromatin by CTCF and promotes formation of topologically associating domains (TADs) via its ability to bind acetylated histones, contributing to CTCF boundary formation and enhancer insulation. Also recognizes and binds acetylated non-histone proteins, such as STAT3. Involved in inflammatory response by regulating differentiation of naive CD4(+) T-cells into T-helper Th17: recognizes and binds STAT3 acetylated at 'Lys-87', promoting STAT3 recruitment to chromatin.
Subcellular location: Nucleus; Chromosome.

Why its pathway is in the library

Epigenetic persistence is the leading hypothesis for why post-drug syndromes endure after the drug is gone; chromatin regulators are therefore priority candidates in any persistence mechanism.
