Record number d056926 Date 06.06.2025 Type M - MESH Topical term CLOCK proteíny UDC D08.811.913.050.134.415.500.049D12.644.360.138.100D12.776.260.103.562D12.776.476.156.200D12.776.930.125.562 Note Basic helix-loop-helix (bHLH) domain-containing proteins that contain intrinsic HISTONE ACETYLTRANSFERASE activity and play important roles in CIRCADIAN RHYTHM regulation. Clock proteins combine with Arntl proteins to form heterodimeric transcription factors that are specific for E-BOX ELEMENTS and stimulate the transcription of several E-box genes that are involved in cyclical regulation. This transcriptional activation also sets into motion a time-dependent feedback loop which in turn down-regulates the expression of clock proteins.
