Summary
Daily rhythms of PERIOD proteins regulate mammalian physiology. This review explores the complex, time-resolved mechanisms and intrinsically disordered nature of PERIOD proteins in the central circadian clock.
Area of Science:
- Chronobiology
- Molecular Biology
- Mammalian Physiology
Background:
- Daily rhythms of PERIOD proteins are crucial for mammalian physiological regulation.
- The molecular mechanisms and genetic circuits governing PERIOD protein function are being elucidated.
- Understanding the time-resolved dynamics of PERIOD proteins remains incomplete.
Purpose of the Study:
- To review the character and controversies surrounding the mammalian PERIOD protein.
- To focus on the intrinsically disordered nature of PERIOD proteins.
- To discuss the time-resolved mechanisms of PERIOD protein function in the circadian clock.
Main Methods:
- Literature review and synthesis of current research on PERIOD proteins.
- Analysis of the role of intrinsically disordered regions in protein function.
- Discussion of ongoing debates and controversies in the field.
Main Results:
- PERIOD proteins exhibit daily rhythms essential for circadian regulation.
- The intrinsically disordered nature of PERIOD proteins is a key aspect of their function.
- Complex molecular interactions and genetic circuits control PERIOD protein activity.
Conclusions:
- Further research is needed to fully comprehend the time-resolved mechanisms of PERIOD proteins.
- The intrinsically disordered nature of PERIOD proteins presents unique challenges and opportunities for study.
- Understanding PERIOD protein dynamics is vital for insights into circadian rhythms, infection, and immunity.

02:19Circadian Rhythms and Gene Regulation
4.0K
The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent...

02:45Biological Clocks and Seasonal Responses
34.5K
The circadian—or biological—clock is an intrinsic, timekeeping, molecular mechanism that allows plants to coordinate physiological activities over 24-hour cycles called circadian rhythms. Photoperiodism is a collective term for the biological responses of plants to variations in the relative lengths of dark and light periods. The period of light-exposure is called the photoperiod.

01:11Understanding Sleep
217
Sleep, an essential biological state, involves significant reductions in physical activity, sensory awareness, and interaction with the environment. This complex physiological process is primarily regulated by specific brain regions, notably the hypothalamus and pons, which govern the sleep-wake cycle or circadian rhythm.
The circadian rhythm, a nearly 24-hour cycle, is deeply influenced by environmental light cues. Light exposure directly affects the hypothalamus, which in turn regulates...

02:11The Cell Cycle Control System
12.0K
The cell cycle is an organized set of events that leads the cell to divide into two daughter cells, each containing chromosomes identical to the parent cell. It is the cell cycle that leads to the formation of an entire organism from a single-cell zygote. Besides, cell division also functions in the renewal or repair of tissues in adult multicellular eukaryotes. For example, in the bone marrow, the stem cells divide to form new blood cells. Although essential for several functions, cell...

02:36Cells Coordinate Growth and Proliferation
4.5K
Cell size is a significant factor impacting cellular design, function, and fitness. There exists some internal coordination by which cells double their masses before division, thus, achieving homeostasis. Coordination between cell growth and proliferation depends on the checkpoints in between cell cycle phases. Loss of coordination or failure in the checkpoint mechanism can drive the cell to uncontrolled growth and loss of cellular function. Like dividing cells that coordinate cellular growth,...

01:27Molecular Factors Affecting Cell Division
3.0K
Several external and internal factors influence the initiation and inhibition of cell division. For instance, the death of nearby cells or the release of human growth hormone (hGH) promotes cell division. In contrast, lack of hGH or crowding of cells can inhibit cell division.
Several proteins function as internal regulators to ensure each cell cycle stage is completed faithfully before proceeding to the next. Regulator molecules may act directly or influence the activity or production of other...
