"Karyopherin" Natural Recordings by Native Speakers
Karyopherin refers to a protein that mediates the transport of molecules, such as transcription factors, between the nucleus and the cytoplasm. It is also known as importin or karyorrhexin. Karyopherin proteins play a crucial role in regulating gene expression by facilitating the transport of specific proteins into or out of the nucleus.
5 Usage Examples for Karyopherin
Karyogamy is a biological process in which two gametes (sperm and egg cells) merge their genetic material to form a single cell, known as a zygote. In other words, it is the process of fusion of the nuclei of two gametes during sexual reproduction, resulting in the formation of a new individual with a unique set of genetic traits.
Karyolymph is the fluid that fills the nucleus of an eukaryotic cell, surrounding the chromatin (DNA) and other nuclear structures. It is a clear, colorless, and protein-rich fluid that plays a crucial role in maintaining the structural organization and integrity of the nucleus.
Karyolyses refers to the fragmentation or destruction of cells, especially in tissue or organs, often resulting in the release of cellular contents into the surrounding environment.
Karyomiton is a rare word that refers to the presence of chromatin in a cell's nucleus. In other words, it describes the material that makes up the chromosomes within the cell's nucleus.
Karyopherins are a family of proteins that play a crucial role in the transport of proteins and other molecules across the nuclear envelope. They are also known as importins and exportins, and are responsible for importing proteins from the cytoplasm into the nucleus and exporting proteins from the nucleus into the cytoplasm. Karyopherins have a specific binding site that recognizes a specific nuclear localization signal (NLS) in the protein being transported, allowing them to selectively transport specific proteins into or out of the nucleus.
Karyoplasm refers to the material that fills the cell nucleus, including the chromosomes, nucleoplasm, and other non-chromosomal structures. It is the gel-like substance that surrounds the chromosomes and plays a key role in maintaining their structure and organization.
Karyorrhectic refers to a type of cell death that occurs in the nucleus of a cell, where the chromatin is fragmented and the nuclear envelope is disrupted, leading to the loss of cellular function and ultimately cell death.
Karyorrhexis is a term used in cell biology that refers to the fragmentation of the nucleus or nucleoli of a cell, typically occurring in response to cellular stress, damage, or apoptosis (programmed cell death). It is often observed in cells that are undergoing programmed cell death, such as during development or in response to tissue injury.
Karyostenosis refers to an abnormal narrowing or constriction of the chromosomes, particularly in a specific part of the chromosome. This term is often used in the context of human genetics and can be a characteristic of certain genetic disorders or syndromes.
