Basic helix-loop-helix family member e41 (BHLHE41) is a gene that encodes a basic helix-loop-helix transcription factor repressor protein in various tissues of both humans and mice.
It is also known as DEC2, hDEC2, and SHARP1, and was previously known as basic helix-loop-helix domain containing class B 3 (BHLHB3).
BHLHE41 is known for its role in the circadian molecular mechanisms that influence sleep quantity as well as its role in immune function and the maturation of T helper type 2 cell lineages associated with humoral immunity.
Only about 1% of the people on earth have this gene.
They sleep about 4 to 6 hours a day yet doesn’t feel tired, instead they are able to do more work and achieve more than average people.
