Ca2läpäisevät

Ca2läpäisevät is a Finnish term that translates to "calcium-permeable" in English. It refers to a property or characteristic of biological membranes or ion channels that allows calcium ions (Ca2+) to pass through them. This permeability is crucial for a wide range of cellular processes.

In biological systems, calcium ions act as important second messengers, mediating signals within cells and between cells. Ca2+-permeable channels, often found in cell membranes, control the flow of calcium ions into or out of the cell, or into intracellular organelles like the endoplasmic reticulum. The opening and closing of these channels are tightly regulated, responding to various stimuli such as electrical signals, chemical ligands, or mechanical stress.

The function of Ca2+-permeable channels is vital for processes like muscle contraction, neurotransmitter release, gene expression, and cell proliferation. Dysregulation of calcium permeability can lead to various diseases, including cardiovascular disorders, neurological conditions, and cancer. Research into Ca2+-permeable channels is ongoing to understand their complex roles and to develop targeted therapies for associated diseases.
