SerpinB3 means serin protease inhibitor, clade B (ovalbumin), member 3. The particularity of Serpin B3 is to target proteases wich have a nucleophilic cysteine instead of serine in their catalytic site.

SCCA1 is a trimeric protein.

The most important part of Serpins is an exposed region of 20 amino acids near the C terminus named the reactive center loop (<scene name='60/604473/The_rcl_loop_scene/3'>RCL</scene>). This <scene name='60/604473/The_rcl_loop_scene/3'>RCL</scene> allow the specificity interaction of the inhibitor for the target protease<ref>PMID : PMC24842</ref>.
