Word History and Origins

Origin of transmembrane¹

First recorded in 1940–45; trans- + membrane

Example Sentences

These gradients, maintained by specialized pumps, require large energy expenditure to generate varying transmembrane electrical potentials.

From Science Daily

"Our research reveals the capability of cells to harness transmembrane ion gradients as a means of communication, allowing them to sense and respond to changes in their surroundings rapidly," said Niraula, an applied research scientist in the Department of Machine Learning.

From Science Daily

Connecting the outside-of-the-cell portion of PD-1 with the inside portion is the transmembrane segment.

From Science Daily

Study results showed that PD-1 forms a dimer through interactions of its transmembrane segment.

From Science Daily

Further immune cell testing in mice showed that encouraging PD-1 to form dimers, specifically in the transmembrane domain but not in its outer or inner regions, increased its ability to suppress T cell activity, while decreasing transmembrane dimerization lowered PD-1's ability to inhibit immune cell activity.
