Immunogens

Immunogen:

A synthesized peptide derived from human TOP2B, corresponding to a region within N-terminal amino acids.

Uniprot:
Gene(ID):
Description:
TOP2B Control of topological states of DNA by transient breakage and subsequent rejoining of DNA strands. Topoisomerase II makes double-strand breaks. Indirectly ivolved in vitamin D- coupled transcription regulation via its association with the WINAC complex, a chromatin-remodeling complex recruited by vitamin D receptor (VDR), which is required for the ligand-bound VDR- mediated transrepression of the CYP27B1 gene. Belongs to the type II topoisomerase family.
