| membrane cofactor p. |
a transmembrane protein, CD46, found in most blood cells, endothelial and epithelial cells, and fibroblasts; it restricts the turnover of complement by acting as a cofactor for factor I–mediated catabolism of C3b and C4b.

| membrane ionic t. |
the theory that the resting potential difference between the inside and outside of the cell is related to (1) the thin, electrically insulating membrane between the cytoplasm and the interstitial conducting medium, which is poorly and variably permeable to diverse ions; (2) the presence of a metabolic cellular pump that promotes the efflux of sodium ions from the cell interior to the outside against its electrochemical gradient and, coupled with this, the influx of potassium ions into the cell against its ionic concentration gradient.
