The major family of calcium-mediated cell-surface adhesion molecules is
A) calmodulins.
B) calsequestrins.
C) cadherins.
D) fibronectins.

Question

Quizplus · Accepted Answer

The major family of calcium-mediated cell-surface adhesion molecules is cadherins. Calmodulins are calcium-binding proteins that regulate a variety of cellular processes, but they are not directly involved in cell adhesion. Calsequestrins are calcium-binding proteins found in the sarcoplasmic reticulum of muscle cells. Fibronectins are a family of extracellular matrix proteins that are involved in cell adhesion and other cell functions, but they are not specifically calcium-mediated.
