monomer |
stomach-specific calpain, nCL-2/calpain 8, is active without calpain regulatory subunit and oligomerizes through C2-like domains. nCL-2 exists in both monomeric and homo-oligomeric forms, but not as a heterodimer with 30K or 30K-2, and that the oligomerization occurs through domains other than the 5EF-hand domain IV, most probably through domain III |

optimal temperature for nCL-2 activity is 20°C. The time courses of nCL-2 activity at various temperatures shows that the initial rates are maximal at 30-37°C, whereas maximal activity is achieved at 15°C |
