 through multiple mechanisms. When BHLHE41 dimerizes with MyoD and E47, it prevents the formation of MyoD-E47 heterodimers, which are functional. When BHLHE41 is sumoylated at K240 and K255, it recruits the histone methyltransferase G9a. G9a then catalyzes repressive histone 3 lysine 9 dimethylation (H3K9me2) at promoter sites of target genes of MyoD. G9a also methylates MyoD, which inhibits MyoD's transcriptional activity.

BHLHE41 and BHLHE40 are transcriptional targets of SREBP-1 (also known as ADD-1) isoforms SREBP-1a and SREBP-1c. After being induced by SREBP-1, BHLHE41 and BHLHE40 have been shown to repress myogenesis by blocking MYOD1 transcription. BHLHE40 and BHLHE41 are also known to alter the expression of several contractile proteins and mitochondrial proteins in skeletal muscle. BHLHE41 and BHLHE40 also repress SREBP-1. This forms a negative feedback loop between SREBP-1, BHLHE40, and BHLHE41 in muscles that runs on a 24-hour circadian cycle, which has a 12-hour offset between SREBP-1 and BHLHE40/BHLHE41. In addition, BHLHE41 is  known to inhibit inflammation and adipogenic differentiation in muscles.

BHLHE41 has been shown to suppress the expression of vascular endothelial growth factor (VEGF) in sarcoma cells and oral cancer cells. BHLHE41 also suppresses cytochrome P450 2D6 (CYP2D6) in hepatocellular carcinoma cells. While BHLHE40 induces apoptosis, senescence, and epithelial-mesenchymal transition (EMT) in tumor cells, BHLHE41 shows a circadian expression and inhibits EMT, apoptosis, and metastasis in sarcoma cells and hepatocellular carcinoma cells. It has been shown that the normal tissue adjacent to colon carcinomas show high levels of BHLHE41 expression. Research is currently examining whether BHLHE40 and BHLHE41 can be used as target genes for chemotherapy.
