The phrase "a key membrane" is correct and usable in written English.
It can be used in scientific or technical contexts, particularly in biology or biochemistry, to refer to an important membrane involved in a specific function or process.
Example: "The research focused on a key membrane that regulates the transport of ions in the cell."
Alternatives: "an essential membrane" or "a crucial membrane".
Desmocollin 2, a desmosomal component, is a key membrane glycoprotein critically involved in cell-cell adhesion and the maintenance of normal tissue architectures in epithelia.
In contrast, every single mammalian TLR is a key membrane receptor upstream of the vertebrate immune signaling cascades.
Specifically, recent evidence suggests β1-integrin is a key membrane receptor for relaying ECM-mediated signals via activating FAK and downstream signals, resulting in enhanced matrix accumulation and tissue formation [45].
Our results further suggest that Rac1 GTPase contributes to induction of oxidative stress in the hippocampus by facilitating activation of NADPH oxidase, a key membrane enzyme that generates O2− ions [6], [12], [29].
Phosphatidylinositol is an important lipid, both as a key membrane constituent and as a participant in essential signaling processes in all plants and animals.
DOI: http://dx.doi.org/10.7554/eLife.00947.026 In this study, we have identified the ERGIC as a key membrane determinant in the biogenesis of autophagosomes.
In all the cases, the identification of aromatic phenylalanines as a key membrane-binding residue is consistent with previous intermolecular Phe-lipid NOE observations.
ABCA1 is a key membrane-associated protein involved in reverse cholesterol transport.
Other LRR-domain containing genes in plants have also been shown to be involved in stress responses under drought stress and as a key membrane-bound regulator of absiscic acid signalling [ 35, 36].
Rab GTPases represent a family of key membrane traffic regulators in eukaryotic cells.
The next aspect of wound healing to explain is the role and reconstitution of the basement membrane (BM)–a key structure of the extracellular matrix (ECM).
