Descriptor English: Gap Junctions
Descriptor Spanish: Uniones Comunicantes
Descriptor uniones comunicantes
Entry term(s) uniones gap
unión discontinua
Scope note: Conexiones entre las células que permiten el paso de pequeñas moléculas y la corriente eléctrica. Inicialmente, las uniones comunicantes se describieron anatómicamente como regiones de yuxtaposición estrecha entre células, con un espacio de separación entre las membranas celulares reducido (1-2 nm). La diversidad de propiedades de las uniones comunicantes se refleja en el número de CONEXINAS, la familia de proteínas que forman las uniones.

Scope note: Connections between cells which allow passage of small molecules and electric current. Gap junctions were first described anatomically as regions of close apposition between cells with a narrow (1-2 nm) gap between cell membranes. The variety in the properties of gap junctions is reflected in the number of CONNEXINS, the family of proteins which form the junctions.
