Based on limited published evidence, BHLHE23 is a basic helix-loop-helix transcription factor that functions as a DNA-binding transcription regulator. UniProt annotations suggest it may act as a transcriptional repressor modulating genes required for pancreatic and neuronal cell differentiation. BHLHE23 is particularly important for rod bipolar cell maturation in the retina 1, where it acts downstream of LHX4 in regulating retinal bipolar cell subtype development. Recent evidence indicates BHLHE23 interacts with lncHAR1B and promotes KLF4 expression, contributing to endothelial cell function and macrophage polarization in wound healing contexts 2.
