CCK22
CCK22 is a label that does not denote a single, widely recognized topic. In the absence of context, it can function as an identifier in chemistry (catalog numbers or compound codes), a gene or protein designation used in a specific research program, a software module or project codename, or a fictional title in media. Because there is no general consensus on its meaning, there is no established encyclopedia entry for CCK22 in major reference works. The intended interpretation depends on the source, discipline, and accompanying documentation.
