Which cell adhesion molecules (CAM) is calcium mediated?: (A) Cadherin, (B) NCAM, (C) IgSF, (D) Fibronectin binding protein
Answer is A. Type of CAM Subtypes Distribution Calcium- dependent 1. Cadherins 2. Selectins 3. Integrins - Most cells including epithelia - Migrating cells E.g.: leucocytes - b/w cells & intercellular substance. About 20 types; each attaching to an extracellular molecule. CALCIUM INDEPENDENT: 1. Neural cell adhesion molecule (NCAM) - nerve cells 2. Intercellular adhesion molecule (ICAM) - leucocytes.
